The need for co-ordinationAll motor starters include devices which provide short-circuit protection,

power switching and overload protection. The devices may be separate

components, such as a set of fuses or an MCCB, a contactor, and a thermal

overload relay. Alternatively, the functions may be combined in a single

component – a fully integrated starter.

Under overload conditions, the overload protection will trip the supply to the

motor in a time which depends upon the current. The greater the current, the

faster the overload will trip, but in the event of a short circuit, it’s response

time is still not fast enough to prevent damage to the motor or starter.

Separate protection against short circuits is, therefore, necessary.

Motor starters may, however, be subjected to a whole range of fault

conditions, from a minor overload to a high-current short circuit. If the

devices making up the starter are not properly co-ordinated, certain levels of

fault may not be correctly handled. Possible consequences include

overheated cables and equipment, with an associated risk of fire; contact

welding in the switching device, rendering it unfit for further service; and

permanent degradation of the characteristics of the overload protection

device, rendering it unreliable – or even unsafe – for future use.

The basic aim of co-ordination is to ensure that the motor starter handles

all levels of fault current safely. The higher types of co-ordination, such as

Type ‘2’, go further and try to ensure that after a fault the starter is still fit for

further use. The load switching contactor may for example have contacts

which are lightly welded, but this weld is easily broken.

After a fault, the motor starter components must be checked. It may be

necessary to replace fuses, check MCCB contacts, and break any tack

welding on the contactor.

To find starters which can be guaranteed to be fit for further service after a fault,

without the need for checking by skilled maintenance staff, it is necessary to

follow Telemecanique’s lead, and go beyond Type ‘2’ co-ordination.

Introduction Evolution

How valid are co-ordination claims?Today compliance with Type ‘2’ co-ordination is

claimed by most component manufacturers. The

component specifier needs to ensure that claims

made by the manufacturer can be backed up.

Statements made in manufacturers’ catalogues such

as “designed in accordance with Type ‘2’

co-ordination” or “Type ‘2’ co-ordination according

to IEC 60947-4-1” are meaningless without any form

or proof. If in doubt, the specifier should ask the

manufacturer to provide copies of the test certificates.

Telemecanique can provide this proof in the form

of test certificates from independant LOVAG

accredited test houses.

Safety in the workplace concerns us all

and, in recent years, its importance has

been emphasised by the introduction of a

whole range of European and national

legislation. One important aspect of this

legislation has been to require proper

co-ordination of the components used in

motor starters. As a result, Type ‘2’

co-ordination, as defined by BS EN

60947-4, has become the accepted

standard for industry today.

The adoption of Type ‘2’ co-ordination

has undoubtedly made a major

contribution to electrical safety, but

Type ‘2’ co-ordination has its limitations.

Nowhere are these more apparent than in

modern continuous process industries

and public utilities, where the cost of

downtime is measured in thousands of

pounds per minute, and where the

accessibility of plant for routine

maintenance is minimal.

In these situations, and many others,

there is a definite need to go beyond the

minimum requirements set by Type ‘2’

co-ordination. Telemecanique is

meeting this need with a comprehensive

range of motor starting solutions which

set new standards for safety,

performance and convenience.

Process applications dependon Telemecanique protectiondevices to provide a safeworking environment.

As long ago as 1985, The Health and Safety at Work

report revealed that, in many electrical installations,

the protective devices were inadequate for the

intended application. Part of the reason for this

was a general lack of understanding of the need

for co-ordination between the components used in

motor starters.

The need for more stringent controls in this area

was highlighted in clause 7.6.1 of BS 5486:1990

(now BS EN 60439-1:1994), which states that

co-ordination, for example, of motor starters with

short-circuit protection devices, must comply with

the relevant IEC standards. The Electricity at Work

Regulations 1989 firmly place the responsibility for

this compliance with the designers, installers and

users of the equipment.

Type ‘2’ co-ordinationThe current standard, IEC 60947-4-1 (BS EN 60947-4-1)

defines levels of co-ordination designated as types

‘1’ and ‘2’.

IEC 60947-4-1 which deals with starters constructed

from separate components, is now complemented

by IEC 60947-6-2 (BS EN 60947-6-2) which covers

Control and Protective Switching (‘CPS’ or ‘Total’

co-ordination) devices, often known as integrated

starters.

The needs of industry

Safety and efficiency are the two key requirements

of modern industry.

To protect people and property, plant must be

designed for safety from the outset. Just as

important, however, it must be maintained in a

safe condition throughout its working life. These

requirements are not optional – they have the full

force of law, and the potential penalties for

non-compliance are severe.

To protect investment, and help users to be

competitive, plant must be productive. Downtime

and stoppages for maintenance must, as far as

possible, be eliminated.

The people and their skillsIn spite of the pressures for safety and efficiency,

today’s industry has staffing levels in design offices

and maintenance departments which are lower than

ever before. Design teams no longer have the time

to create individual solutions for each project, and

hard pressed maintenance staff have little time to

spend tracing and correcting faults and replacing

components where necessary.

Furthermore, skill levels in many plants are declining.

In this competitive age, no company can afford to

employ specialist staff whose skills will be needed

only occasionally. Yet, to meet the twin requirements

of safety and efficiency, modern equipment is

necessarily complex. How can non-specialist staff,

working under constant time pressure, be expected

to cope?

The black boxThe answer is to let the equipment manufacturer

take care of the complexity. Working to, and beyond

the latest standards, expert equipment

manufacturers like Telemecanique can produce

equipment which intrinsically satisfies industry’s

requirements for safety and efficiency.

For specifiers and users, such equipment can be

treated as a black box. To use it safely and

effectively, it’s only necessary to know what it does,

and what its limitations are. Detailed knowledge of

the equipment’s internal features is totally

unnecessary.

Excellent examples of black-box products are the

fully integrated starters in Telemecanique’s Integral

range. Each Integral starter offers isolation, short-

circuit protection, power switching and overload

protection in a single device. Co-ordination is

automatic – Telemecanique has built it in – and the

starter’s performance is guaranteed under all

operating conditions within their specification.

Fit and forgetThe black-box concept is an ideal solution for the

plant designer and specifier, but what can be done

about maintenance? Clearly, the answer is for

manufacturers to produce products which require no

maintenance but, for motor starters, this is quite a

challenge. What about fuse replacement or contact

welding under fault conditions?

By going beyond Type ‘2’ co-ordination, however,

Telemecanique has completely solved the problems

of starter maintenance. Telemecanique Integral CPS

starters are not just black boxes, they’re also true fit-

and-forget products. They will never need specialist

attention during their exceptionally long working lives

– even if they are subject to overload or short circuit

fault conditions.

More flexible, more intelligentFully integrated CPS starters are the ideal choice for many applications but,

for large (above 63A) or especially important drives, or complex systems, a

solution which offers flexibility may be needed. In particular, these drives may

need advanced motor protection incorporating, for example, underload and

earth-leakage detection. In modern installations, the starters may also need the

intelligence to collect data, and to communicate directly with programmable

controllers and supervisory computer systems.

Telemecanique offers solutions which meet these requirements, and many

others, without sacrificing the benefits of the black box approach. Though the

starters now incorporate separate components, provided that Telemecanique’s

expert selection advice is followed, they are guaranteed to meet the

requirements for Type ‘2’ co-ordination. No complicated calculations or

characteristic comparisons are needed. And, as with Telemecanique’s integrated

solutions, maintenance requirements are minimal.

Meeting the needs of industryTelemecanique understands the needs of industry for safety and efficiency, and

has developed a range of motor starting solutions which go beyond the

minimum requirements of Type ‘2’ co-ordination to meet those needs in every

application. Telemecanique has the expertise you can rely on to solve your motor

starting problems.

Integral control and protectiveswitching devices (CPS), offer aguarantee of no contact welds

In the United Kingdom, the

fundamental guidelines for

safety in the workplace are the

Health and Safety at Work Act

of 1974 and, for matters

concerned with electricity,

the Electricity at Work

Regulations of 1989. These

regulations apply to everyone,

whether they be suppliers or

manufacturers of equipment,

or simply users.

For those involved with the design, manufacture and

installation of equipment, the Supply of Machinery

(Safety) Regulations 1992 lay down further

requirements. For end users of equipment, the

Health and Safety at Work Act and the Electricity at

Work Regulations are supplemented by the

Provision and Use of Work Equipment Regulations

1992, often referred to as PUWER.

76

Legislation and standards

Other standardsThe 16th Edition of the IEE Wiring Regulations,

which have now been given the status of a British

Standard (BS 7671), establish basic requirements for

electrical installations in the UK. Rule 435-01-01 of

the 16th edition is particularly concerned with

co-ordination, and states:

435-01-01 The characteristics of each device for

overload current protection and for fault current

protection shall be co-ordinated so that the energy

let-through by the fault current protective device does

not exceed that which can be withstood without

damage by the overload current protective device.

For applications involving motor starters, this once

again suggests that reference should be made to

the co-ordination requirements of BS EN 60947-4-1

or BS EN 60947-6-2 and the requirements for motor

starters in panels built to BS EN 60439-1.

Duty holdersAccording to the Health and Safety at Work Act, every employee has a

responsibility to ensure the safety of others, and their own personal safety, in the

workplace. Other regulations also define duties and responsibilities.

Under the Supply of Machinery (Safety) Regulations, for example, the duty

holder is defined as any person, within a particular area, responsible for his or

her own safety, and the safety of others, within the working environment. This

includes designers, engineers, technicians and users of machinery.

The Provision and Use of Work Equipment Regulations clearly and

unambiguously identify the employer as the person whose duty it is to ensure

that the requirements of the regulations are met.

In each and every case, the duties and obligations have the full force of law, and

failure to meet them may lead to severe penalties, including imprisonment. This

makes it very much in everyone’s interest – whether designer, specifier or end

user – to ensure that equipment complies with all of the relevant standards.

The Supply of Machinery

(Safety) RegulationsIn meeting their obligations under these regulations,

designers will initially be guided, in electrical

aspects, by BS EN 60204-1, Safety of Machinery –

Electrical Equipment of Industrial Machines. They

will also need to take into account those specific

types of equipment and areas of design which have

their own standards, such as BS EN 60947-4-1

which covers conventional motor starters, and

BS EN 60947-6-2 which covers starters constructed

as fully integrated Control and Protective Switching

(CPS) devices.

Provision and Use of Workplace

Equipment RegulationsUnder the provisions of these regulations, employers

are legally obliged to ensure that work equipment,

existing or new, is installed and used in line with the

requirements of the regulations. Among the specific

provisions of the regulations are requirements for

adequate maintenance, and ensuring that all staff are

properly trained. Specific hazards, such as the risk of

fire, overheating and explosion, are also addressed.

One of the most important steps toward

demonstrating compliance is to show that all

elements of the installation meet the requirements of

the specific standards which apply to them, such as

BS EN 60947-4-1 and BS EN 60947-6-2, as already

mentioned, for motor starters.

98

Standards for motor starters BS EN 60947–4–1 and BS EN 60947–6–2

BS EN 60947–4–1 Electro-mechanical contactors and motor starters

BS EN 60947–6–2 Control and Protective Switching devices (CPS)

This standard defines two levels of co-ordination.

Type ‘1’ provides complete protection for individuals

in the case of a fault, but does not directly limit the

amount of damage which may be caused to the

starter, meaning costly downtime after a fault,

together with the inconvenience and expense of

having to replace damaged equipment.

Type ‘2’ co-ordination also offers complete protection

for individuals against injury, in the event of a fault,

but additionally offers an improved level of protection

for the starter, potentially reducing plant downtime.

The table overleaf shows the tests which are

required for Type ‘2’ co-ordination, but it’s important

to note that only the ‘r’ test is compulsory.

Manufacturers who have only carried out the ‘r’ test

can still claim Type ‘2’ co-ordination – there is no

obligation to carry out the subsequent making and

breaking tests to ensure that the starter is fit for

further service.

Telemecanique, however, goes beyond the minimum

requirements of BS EN 60947-4-1, and carries out

all of the prescribed tests on every product

combination for which Type ‘2’ co-ordination is

claimed. Users of Telemecanique products can not

only rely on full co-ordination under all conditions,

they can also be sure that, after a fault, their

installation will remain fit for further service.

This standard, for integrated CPS starters, ensures

the highest level of co-ordination, with comprehensive

protection for personnel and equipment. In addition,

as the table shows, it requires comprehensive

performance testing, involving thousands of operating

cycles, both before and after short-circuit and

making/breaking capacity tests.

The tests detailed in BS EN 60947-6-2 closely

resemble the normal operating conditions of the

starter. Users selecting products which conform

with this standard can, therefore, be sure of black-

box convenience with fit-and-forget performance.

BS EN 60947-6-2 sets new standards which go way

beyond Type ‘2’.

BS EN 60947-4-1 covers contactors and motor

starters. Its provisions relate specifically to motor

starters assembled from separate components –

typically a set of fuses or magnetic-only MCCB, a

contactor, and an overload relay. Starters comprising

other combinations of components are, however,

not excluded.

BS EN 60947-6-2 relates specifically to control and

protective switching (CPS) devices, which are more

usually referred to as integrated starters. Because no

welding of contacts is allowed under any overload or

short circuit fault condition, this standard does not

usually cover starters made up of separate

components, such as a motor protection circuit

breaker and a contactor, mounted on a common

baseplate, even though these are sometimes loosely

described as "integrated starters".

BS EN 60947-6-2 applies only to starters which are

designed, manufactured and marketed as a single,

totally integrated unit meeting all the requirements of

the test sequences specified. This distinction is

important, as the standard demands higher levels of

performance than those required by BS EN 60947-4-1

for starters assembled from separate components.

For example, BS EN 60947-6-2 requires no contact

welding, and a guaranteed continuity of electrical life

even after a number of fault clearances.

IEC 61459 Technical reportThis technical report, published by the International

Electrotechnical Commission, provides guidance on

the use of alternative Short Circuit Protective

Devices (SCPDs) in motor starter combinations

based on the information provided by a certified

tested combination.

The main criteria to be taken into account are:

■ The I2t let through energy of the alternative

SCPD must not be greater than that used in

a tested combination

■ The Ip current peak of the alternative SCPD

must not be greater than that used in a tested

combination

■ The SCPD/overload crossover point must be

suitable for the starting duty, plus overload and

contactor protection.

Co-ordination test requirements – a comparison

Direct on line motor startersTelemecanique offers a wide range of motor starters

having certified Type ‘2’ co-ordination, these being

mainly for operation at 380/415V. In the same way

that IEC 61459 provides guidance on using Short

Circuit Protective Devices other than the certified

combination, the same criteria can be used to

determine combinations for use at other voltages.

This is achieved by taking account of the let through

energy and peak current values of the SCPD at the

alternative voltage, used with a contactor suitable

for use at that voltage, enabling a suitable

contactor/overload combination to be selected.

Star-delta motor startersThe traditional position for the thermal overload in a

star-delta starter is in the delta loop, with a current

setting of 0.58 that of the motor full load current.

Additionally the contactors are selected with an AC3

rating for this delta loop current.

In order to achieve Type ‘2’ co-ordination in

accordance with the IEC 61459 recommendations it

is necessary to base the component selection on

the results of tested combinations. Where this

combination has included a thermal overload, in

which the impedance of the device has an influence

on the energy let through under short circuit

conditions, this must be taken into account when

selecting components.

With a starter based upon a traditional circuit the

following points should be considered:

The overload in the delta-loop, is in series with only

one of the two contactors in circuit when the motor

is running.

The contactors may be of a smaller rating than

those for a DOL starter having the same kW rating.

In the case of an overload having directly connected

bi-metallic elements, such as those in

Telemecanique’s ‘D’ range, it is necessary to

simulate the conditions of a tested DOL

combination. This is achieved by connecting the

thermal overload, fully rated for the motor full load

current, directly after the SCPD. The contactors

must be of the same rating as that used with the

overload in the DOL combination. The rating of the

SCPD may be of a lower rating in the case of a fuse,

but in the case of an MCCB will be of the same

rating as for the DOL combination.

Where the overload is of the CT operated bar

primary type, such as the LR9-F type or the LT6

used with external CT’s, the short circuit Type 2

tests will effectively be a SCPD/contactor

combination. In this case a CT operated overload

can be retained in the traditional delta-loop position.

The contactors used in the combination may be of a

smaller rating than those for the DOL combination,

but must be suitable for use with the SCPD selected

for starting duty of the starter.

The following symbols are used in defining the operating sequences:

O represents a breaking operation (Opening).

CO represents a manual making operation (Closing) followed by a breaking operation

(Opening). If the starter cannot be operated manually, the sequence rCO is used instead.

rCO represents a remote-controlled making operation (Closing) – by energising the control

circuit – followed by a breaking operation (Opening).

Electronic technology solutions

Co-ordination which goes beyond Type ‘2’ offers

many benefits, including improved safety, better

plant availability, and a reduction in the need for

skilled maintenance. Sometimes, however, today’s

industry needs even more from its motor starters,

particularly when large drives, or those which are

especially critical to the operation of the plant, are

involved. In these applications, modern electronic

chip-based technology provides the solutions.

Better protectionModern thermal overloads based on bi-metal

technology provide excellent protection for motors

in many applications, but they are not without their

limitations. For example, they do not work well with

drives having long run up times, they consume an

appreciable amount of power, they generate heat

within the control enclosure and, particularly if they

need to be used with current transformers, they

require a lot of space.

Electronic chip-based overloads not only solve all of

these problems, they also offer more tightly

controlled trip characteristics and better thermal

modelling. The result is precision protection well

matched to modern motors, which have

substantially less capability to withstand overloads

than their bulkier predecessors.

Electronic overloads need no longer be costly or

complicated. Products in Telemecanique's new

LR9-D and LR9-F range cost the same as the

bi-metal equivalents which they replace, and are just

as simple to use. They now mount directly onto

the contactor.

More protectionSometimes, motor drive systems need more than

just thermal overload protection and, once again,

electronic chip-based technology can help. The

Telemecanique LT6 multifunction digital protection

relay, for example, combines precision thermal

protection with protection against phase imbalance,

phase failure, earth fault and overheating (PTC) with

inbuilt optional protection against protracted run-up

time, underload, excessive torque, incorrect phase

sequence, and out-of-tolerance supply voltage.

Even in the most critical applications, the LT6

normally provides all the protection that’s needed.

CommunicationEffective management of today’s industrial plant

depends on knowing what’s going on, and being

able to exercise control. It’s important to know just

why problems have occurred, so that they can be

avoided in future.

Communication is the key. Sophisticated electronic

protection relays, such as the LT6, have facilities for

communicating with programmable controllers and

control systems. They can provide information on

faults, and details of operating conditions, allowing

trends to be detected and analysed. Even better,

they can provide warnings of an impending trip

condition, giving the control system or the plant

operator time to take avoiding action, and to

eliminate plant downtime.

Nor is the communication all one way.

Telemecanique LT6 relays can be remotely re-

configured, allowing, for example, the control

system to set different parameters automatically

when a plant is switched from manufacturing one

type of product to another.

Expertise in startersElectronic technology is improving the functionality,

and changing the role of the motor starter but, to

get the best from such fast developing technology,

requires the support of a dependable partner.

Telemecanique has the products and expertise to

provide that support, now and in the future.

Whatever your motor starting requirements,

Telemecanique offers a range of proven solutions

matched to the needs of modern industry.

Single component Integral controland protective switching device(CPS), offering a guarantee of nocontact welds

Component co-ordination in motor startersSelection of components for use in a motor starter combination should be based

on the following criteria:

Thermal overload selected to allow a current setting for the rated full load current

of the motor.

SCPD (Fuse, circuit breaker or CPS device) selected to provide an

overload/SCPD crossover current value which allows correct motor starting,

protection of the overload and contactor under short circuit conditions, and is

suitable for use at the prospective short circuit current.

Selection of a contactor having a suitable AC3 rating with a breaking capacity

greater than the SCPD/overload crossover current, and, when used with class 20

or class 30 overloads, an adequate time/current withstand capability.

Solutions from Telemecanique

Single-component solutionsFor the vast majority of straightforward motor

starting requirements up to 30kW, fully integrated

single-component products in the Integral range are

an ideal and economical choice. Integral Control and

Protective Switching (CPS) devices offer a true

black-box solution, with fit-and-forget performance,

even after being subjected to fault conditions.

All products in the range are fully tested to

BS EN 60947-6-2, and automatically offer total

co-ordination under all operating conditions.

Selection tables are provided on pages 22 and 23.

Two-component solutionsMany users prefer the convenience of a resettable

circuit breaker to the use of replaceable HRC fuses.

In this situation, Telemecanique contactors, used in

conjunction with GV2 or GV7 motor circuit breakers

having a motor overload characteristic, provide an

attractive solution. GV2 and GV7 motor circuit

breakers are specifically designed for use in motor

starter circuits, and combine overload and short-

circuit protection in a single device. Full co-

ordination is assured for the tested and proven

combinations listed in the tables on pages 20 and 21.

Three-component solutionsTelemecanique contactors, used in conjunction with

Merlin Gerin magnetic-only MCCBs or GEC Alsthom

HRC fuses, and LR2 bimetal thermal or LR9

electronic overload relays, offer an exceptional

versatile choice of motor starting options. The range

of options is increased still further by choosing an

LT6 multifunction protection relay in place of

standard overloads. Details of tested and proven

combinations are provided in the tables on pages

18, 19 and 20.

The future

SafetyIn modern industry, all practicable steps must be

taken to ensure the safety of personnel. Safety is

not an option – it’s a legal obligation backed by the

full force of the law. Every employer and employee

has a duty to ensure safety.

Motor starters which feature Type ‘2’ co-ordination

contribute significantly toward ensuring safety, but

remember that Type ‘2’ may not be the complete

answer. Telemecanique has the starter solutions

which go beyond Type ‘2’.

Reliability and continuity of serviceToday’s competitive environment means that no

business can afford to have plant out of action.

Neither can it afford to support a large maintenance

team, or to employ specialists whose knowledge is

only occasionally required. The logical alternative is

to employ dependable equipment, which requires

little or no maintenance.

Motor starters which feature Type ‘2’ co-ordination

provide a partial answer, but Telemecanique CPS

starters go beyond Type ‘2’. They guarantee reliable

operation under all conditions, and offer true

fit-and-forget maintenance-free performance.

Future-proofingModern industry needs the support of new

technology to help it compete in fast-changing

world markets. Telemecanique motor starters

incorporating electronic chip technology are now

available, which give better and more versatile

protection than ever before, reducing the incidence

of costly failures.

This technology also makes it possible for starters

to communicate, warning of potential faults before

they happen, and allowing protection parameters to

be changed. With their advanced chip technology,

Telemecanique starters become a fully integrated

and intelligent part of the plant’s control system.

■ Telemecanique offers the UK’s widest range of

motor starting options, whether the application

demands a one-, two- or three-component

solution. Solutions provide co-ordination to Type

‘2’ requirements – and beyond.

■ Telemecanique has built its unrivalled expertise

into every motor starter, so as to make life easy

for designers and safe for users.

■ Only Telemecanique offers integrated CPS

starters tested and certified to BS EN 60947-6-2,

the true fit-and-forget black-box products.

■ Telemecanique products are proven in service

and have been tested and certified by accredited

LOVAG authorities. Ask to see the proof!

■ Telemecanique products are readily available

through the nationwide Telemecanique distributor

network.

■ Every Telemecanique starter, and every

Telemecanique product, is backed by the

unrivalled expertise and support of the Schneider

Electric organisation.

■ Where Type ‘2’ co-ordination is required for

starting methods other than DOL (star delta, soft

start, etc.), Telemecanique can provide guidance

on the components needed, which will come as

close as is possible to the tested certified

Type ‘2’ solutions.

Clause 8.3.4.2A starter covering a range of motor ratings and equipped with

interchangeable overload relays shall be tested with the overload relay

with the highest impedance (0.55kW) and the overload relay with the

lowest impedance (4kW) together with the corresponding SCPD’s.

For these ratings use the higher combination with the overload relay set to

the required full load motor current.
