GENERAL CONSTRUCTION

Wylex MCBs are of the thermal-magnetic current limiting type, havinga compact construction which has been achieved by not onlyminimising the number of parts but also the number of welded jointsand connections. Critical material selection ensures reliability anddurability. Typical of this is the choice of silver graphite for the fixedcontact.The MCB has an easy to operate handle with a trip-free togglemechanism – so even when the handle is held in the ‘on’ position theMCB is free to trip.

AMBIENT TEMPERATURE CONSIDERATIONS

Wylex MCBs are calibrated to meet the requirements of BS EN 60898,30°C Ref Calibration Temperature.At other temperatures the following rating factors should be used:

At 60°C 0.9 At 20°C 1.0 At 0°C 1.1

Adjacent thermal-magnetic MCBs should not be continuously loaded ator approaching their nominal rated currents when mounted inenclosures. It is good engineering practice to apply generous deratingfactors or make provision for adequate free air between devices.In these situations, and in common with other manufacturers, werecommend a 66% diversity factor is applied to the MCB nominal ratedcurrent where it is intended to load the MCBs continuously (in excessof 1 hour).

METHOD OF OPERATION

1 Moderate overload conditionsDetection of moderate overload conditions is achieved by the use of athermo-metal element which deflects in response to the currentpassing through it. The thermo-metal element moves against the tripbar releasing the trip mechanism.

2 Short circuit conditionsWhen the current flowing through the MCB reaches a predeterminedlevel, the solenoid directly pulls in the plunger which forcibly separatesthe contacts and simultaneously releases the trip mechanism.3 Establishment of arc between fixed and moving contactsAs the moving contact moves away from the fixed contact, an arc isestablished. The arc runs along the arc runner to the arc chamberwhere it is split up between the plates and extinguished.The low inertia and consequent high speed of the moving contact has alimiting effect on the flow of fault current. The rapid development ofthe arc, together with its accelerated extinction in the arc chamber,gives a typical operating time of 3.5–5 milliseconds.

CURRENT LIMITING ACTION

The high speed current limiting action ensures that the MCB operatesbefore the full prospective fault current is allowed to develop.Under fault conditions, damage can be sustained to the installation andassociated equipment due to the amount of energy that passes beforethe current is completely interrupted. The total energy let-throughdepends on the value of current and the time for which it flows, and isdenoted by the symbol I2t. The high speed current limiting action ofMCBs ensures that the energy let-through and any subsequent damageis minimised. This reduced energy let-through assists greatly with bothback-up and discrimination considerations.

BACK-UP PROTECTION

Back-up protection is required only if the prospective short circuitcurrent at the point of installation exceeds the breaking capacity of theMCB. When providing back-up protection consideration must be givento discrimination between the MCB and fuse.

DISCRIMINATION

It is desirable that the protective device nearest the fault shouldoperate first. The low energy let through of modern MCBs providesbetter discrimination with HRC fuse back-up than is given by earliertypes of MCBs.

TRANSIENT EARTH LEAKAGE CURRENTS

All Wylex residual current devices incorporate a high level of immunityto tripping when subjected to transient earth leakage currents.Such transients can occur when there is a significant level ofcapacitance to earth as can result from cable capacitance (particularlyMICC) or RF filter networks. Wylex RCDs are therefore lesssusceptible to nuisance tripping due to transient earth leakagecurrents.

RESIDUAL TRIPPING CURRENTS

10mAUsed in special applications where additional protection against contactis essential due to the nature of the installation.30mATripping current designated by the IEE Wiring Regulations to provideadditional protection against direct contact shock, ie socket outsidethe equipotential zone. TT systems, caravan installation, etc.100mASuitable for use against indirect contact shock or where protection isprovided to guard against firehazard, etc, rather than to provideadditional protection to personnel, and where the earthingrequirements need supplementing by RCD protection.100mA time delaySuitable for use when total RCD protection is required to supplementthe system earthing and where local 30mA RCDs are used to giveadditional protection against direct contact. The time delay RCD willdiscriminate with the 30mA RCD.300mA For use in large installations where plant and equipment protection arethe main considerations and high levels of earth leakage areexperienced.

OPERATION

The RCD employs the current balance principle which involves thesupply conductors to the load (phase and neutral) being wound onto acommon transformer core to form the primary windings.Under healthy circuit conditions, the current in the phase conductor isequal to the current in the neutral, and the vector sum of the currentis zero.In the event of an earth fault, an amount of current will flow to earth,creating an out of balance situation in the transformer assembly.This out of balance is detected by the secondary winding of thetransformer and at a pre-determined level of out of balance willactivate the trip mechanism.Single phase and neutral or three phase and neutral units (suitable for3 or 4 wire systems) are available, the latter being suitable for balancedor unbalanced 3 phase loads.The RCD trip mechanism will operate at a residual current of between50–100% of its rating tripping current (sensitivity).

APPLICATION GUIDE FOR RESIDUAL CURRENT DEVICES

A test button is provided on all RCDs to enable the operation of thedevice to be checked.It is recommended that an RCD is tested regularly.(See BS 7671 Regulation 514-12-02).

1 Usually no reaction effects.

2 Usually no harmful physiological effects.

3 Usually no organic damage to be expected. Likelihood of muscular contraction and difficulty of breathing, reversible disturbances of formation andconduction of impulses in the heart, and transient cardiac arrest without ventricular fibrillation increases with current magnitude and time.

4 In addition to the effects of zone 3, probability of ventricular fibrillation increased up to 5% (Curve C2), up to 50% (Curve C3) and above 50%beyond Curve C3. Increasing with magnitude and time, pathyphysiological effects such as cardiac arrest, breathing arrest and heavy burns may occur.

FAULT CURRENT SENSITIVITY

Semi-conductor devices are now incorporated in equipment usedthroughout industry, commerce and in the home. Typically, the purposeof these semi-conductor devices is for monitoring and controllingindustrial equipment, eg speed controls for small motors andtemperature controls, along with extensive use in computers, VDUs,printers, washing machines, etc.As the equipment is fed from the mains electrical supply, in the eventof an earth fault the presence of semi-conductors may result in thenormal ac waveform being replaced by a non-sinusoidal fault current. Insome cases the waveform may be rectified or chopped. Thesewaveforms are said to contain a pulsating dc component which caneither partially desensitise or totally disable a standard Type AC RCD.New International standards IEC 1008 (RCCBs) and IEC 1009(RCBOs) divide RCDs into two performance classes:

Type ACRCDs for which tripping is ensured for residual sinusoidal alternatingcurrents, whether suddenly applied or slowly arising.

Type ARCDs for which tripping is ensured for residual sinusoidal alternatingcurrents and residual pulsating direct currents, whether suddenlyapplied or slowly arising.

To ensure the correct level of protection, check for the followingsymbols:

CONSTRUCTION

Wylex NH MCB distribution boardenclosures are fabricated in heavy gauge steeland are rust protected. The powder coatingprocess uses an epoxy/polyester compoundwhich is stoved to produce a durable finishhighly resistant to both weathering andmechanical damage. Incorporated in thedistribution boards are multi-terminal earthand neutral bars labels. They are designed forease of installation and have ample wiringspace.

The WYLEX PSB miniature circuit breakersare rated at 10kA and are of the fault limitingtype.

When a short circuit occurs, the current

operates a solenoid which trips the mechanism

and forces the moving contact away from the

fixed contact. The arc generated is forced into

an arcing chamber which incorporates splitter

plates, to divide and cool it, reducing the total

operating time to less than 5ms, This high

speed operation substantially reduces the ‘let

through’ energy (I2t) in comparison with ‘zero

point extinguishing’ or ‘half cycle’ MCBs,

keeping additional damage at the point of the

fault to a minimum. Additionally this allows

discrimination with HRC fuses at high fault

levels.
