THE NH RANGEThe NH range of consumer units providescontemporary styling with particular attentionto installation features including:

● Generous cable preparation room with neutral and earth bars mounted on the top of the enclosure

● Supplied complete with incoming devices and fixed busbar system for speedy installation

● Insulated versions with side entry cut outs profiled to accept mini trunking and large segmented rear cable entries to allow trimming to the precise cable entry size

● Raised interior for maximum wiring space

● Circuit identification labels providing clear understanding of outgoing ways

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.

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).

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.

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.

CONSTRUCTION

Wylex NH MCB distribution boardenclosures are fabricated in heavy gauge steeland are rust protected and highly resistant toboth weathering and mechanical damage.Incorporated in the distribution boards aremulti-terminal dual earth and neutral bars.They are designed for ease of installation andhave ample wiring space.

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

When a short circuit occurs, the currentoperates a solenoid which trips the mechanismand forces the moving contact away from thefixed contact. The arc generated is forced intoan arcing chamber which incorporates splitterplates, to divide and cool it, reducing the totaloperating time to less than 5ms, This highspeed operation substantially reduces the ‘letthrough’ energy (I2t) keeping additional damageat the point of the fault to a minimum.Additionally this allows discrimination withHRC fuses at high fault levels.
