E Improved Performances
In addition to the increased number of contact combinations, the NEW Gewiss
contactors guarantee high technical performance and electrical endurance for the
operating frequency according to the utilization category and power of the device.
24V AC/DC and 230V AC-220 DC control coil voltage versions available.
Additional Accessories
The NEW Range of contactors can be equipped with Gewiss auxiliary contacts to
enable remote indication of the contactors status. It is also possible to use sealing
terminal covers which prevent access to terminal connections and therefore
remove the possibilities of direct contact with live parts.
90 AM RANGE
Silent Operation
With thanks to the new technology of the coil the entire range is suitable for many
applications that require silent operation, for example: Hospitals, Hotels, Retirement
homes etc.

CIRCUIT IDENTIFICATION
every contactor has a clear label holder that enables circuit
identiication for each device.
MANUAL CONTROL VERSIONS
On the front of every device there is a mechanically
operated indicator that represents the position of the
internal contacts:
- neutral colour: un-switched contacts
- red colour: switched contacts
HARMONISED RANGE
The new CTr range can be perfectly integrated with the
other geWISS protection devices, providing a pleasant
aesthetic result.
VISUAL INDICATION
All manual control contactors have a lever switch on the
front of the device that enables manual control of the
operational functions:
- Automatic
- Isolate (permanently switched of)
- Temporary operation

The table below shows a brief description of each utilization category according to EN 61095. For the performance of the Gewiss
contactors according to the utilization category, please see the application note.
UTILIZATION CATEGORIES

90 AM RANGE
MODULAR CONTACTORS CTR
In general, the technical data of Gewiss contactors refer to the AC-1 or AC-7a utilization category. If the type of electrical load
doesn’t belong to these categories, the current and as a consequence the power of the load, must be derated according the
following table.

STOP
START
A typical automatic control circuit for start-stop of an engine consists of a device
for the protection of overcurrents (MCB or motor protection switch), a contactor (to
allow opening and closing of the power circuit) and an auxiliary circuit consists of
buttons which energize and de-energize the contactor’s coil (typically a NO button
start and a NC stop button such as GW 96 565)
The choice of the contactor most suitable for this type of application must not only be inluenced by the power of the engine
but it’s important even to consider the utilization category in order to know its electrical endurance in reference to the number
and frequency of operations. In the EN 60947-4-1 standard there are 4 utilization categories regarding to motor control, exactly:
• AC-1 for switching of slightly inductive loads (e.g. electric heating, power distribution)
• AC-2 for starting, switching of, plugging, inching of slip-ring motors (e.g. hoisting, handling, crusher, rolling-mill)
• AC-3 for starting, switching of running of squirrel-cage motors (e.g. pumps, fans, air-conditioning, conveyors, presses etc…)
• AC-4 for starting, switching of, plugging, inching of squirrel-cage motors (e.g. hoisting, handling, crusher, rolling-mill)
The most common type of method to start and stop the running of a motor corresponds to the AC-3 category i.e. the control
device drives the starting current and stops the running of motor when the motor is supplied by the rated current.
In the case of AC-4 utilization category, the contactor must be oversized because it works under heavy-duty conditions since
switching of of running happens during start-up period of the engine instead during regular working period.
Below there is an example for the choice of the most suitable contactor considering every factor described previously:
• Squirrel-cage motor control (AC-3 utilization category)
• Operational voltage: 400V three-phase
• Motor power: 11kW
• No. of operations: 100 per day
There are two options for motor controlling:
1.CTR40: at max operiting power of 11kW, max number of operations is 150,000. Therefore the contactor’s lifetime is 150,000 /
100 = 1,500 days.
2.CTR63: from durability diagrams it’s possible to know the number of operations depending on motor power that is about
270.000 operations. Therefore the contactor’s lifetime is 270,000 / 100 = 2,700 days.

Versions with manual control have on the front face a built-in toggle handle switch which enables to set the operating mode of
contactor.
A: AUTOMATIC operating mode, working as normal contactor. Therefore the switching of contacts happens when the coil is
energized and is disenergized.
O: PERMANENT SWITCHED OFF control voltage mode, the contacts are locked mechanically.
I: TEMPORARY RUNNING mode. The contacts switch when the control voltage is not applied. When the control voltage is
applied the toggle handle switch is automatically set to position A maintaining the previuos contacts status.
Versions with manual control are used when it’s necessary to switch the contacts without considering their status and leaving
out the basic function of normal contactors. In fact it’s always possible to switch the contacts even when control voltage is not
applied.
Contactors with manual control enable switching depending on tarif (selection of most convenient tarif ). Moreover they are
suitable to test the working of product before starting or for maintenance operations (such as the replacement of lights) to ensure
the safety of the operator. In the end it’s possible to avoid the installation of change-over switch (manual/auto) or three-way line
switch (manual/0/auto) often required as accessory for the control of motor, pump and fans.
