Founded in 1897, Wylex introduced the

first ‘consumer unit’ to the

electrical

industry, this original design was the

forerunner to the

‘Standard Range’,

which is still in wide use today.

From its base at

Wythenshawe, through

a policy of continuous design

improvement,

Wylex has developed a

comprehensive range of Domestic,

Commercial

and Industrial circuit

protection devices based on quality and

close attention to the practical

requirements of the contractor including

the fundamental requirements of

electrical safety embodied in the

relevant

British and International Standards

including IEE Wiring

Regulations.

THE NH RANGE

CUSTOM BUILT

To meet the ever changing requirements and designs

of the modern electrical installation, Wylex offers a

service where the standard range of products can be

modified to specific customer needs.

Our technical services and engineering teams

can assess the feasability of a product

requirement whilst our modern manufacturing

facilities

will produce a high quality competitive solution.

The NH range of consumer units provides

contemporary styling with particular attention

to 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, having

a compact construction which has been achieved by not only

minimising the number of parts but also the number of welded joints

and connections. Critical material selection ensures reliability and

durability. Typical of this is the choice of silver graphite for the fixed

contact.

The MCB has an easy to operate handle with a trip-free toggle

mechanism – so even when the handle is held in the ‘on’ position the

MCB 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 at

or approaching their nominal rated currents when mounted in

enclosures. It is good engineering practice to apply generous derating

factors or make provision for adequate free air between devices.

In these situations, and in common with other manufacturers, we

recommend a 66% diversity factor is applied to the MCB nominal rated

current where it is intended to load the MCBs continuously (in excess

of 1 hour).

METHOD OF OPERATION

1 Moderate overload conditions

Detection of moderate overload conditions is achieved by the use of a

thermo-metal element which deflects in response to the current

passing through it. The thermo-metal element moves against the trip

bar releasing the trip mechanism.

2 Short circuit conditions

When the current flowing through the MCB reaches a predetermined

level, the solenoid directly pulls in the plunger which forcibly separates

the contacts and simultaneously releases the trip mechanism.

3 Establishment of arc between fixed and moving contacts

As the moving contact moves away from the fixed contact, an arc is

established. The arc runs along the arc runner to the arc chamber

where it is split up between the plates and extinguished.

The low inertia and consequent high speed of the moving contact has a

limiting effect on the flow of fault current. The rapid development of

the 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 operates

before the full prospective fault current is allowed to develop.

Under fault conditions, damage can be sustained to the installation and

associated equipment due to the amount of energy that passes before

the current is completely interrupted. The total energy let-through

depends on the value of current and the time for which it flows, and is

denoted by the symbol I2t. The high speed current limiting action of

MCBs ensures that the energy let-through and any subsequent damage

is minimised. This reduced energy let-through assists greatly with both

back-up and discrimination considerations.

BACK-UP PROTECTION

Back-up protection is required only if the prospective short circuit

current at the point of installation exceeds the breaking capacity of the

MCB. When providing back-up protection consideration must be given

to discrimination between the MCB and fuse.

DISCRIMINATION

It is desirable that the protective device nearest the fault should

operate first. The low energy let through of modern MCBs provides

better discrimination with HRC fuse back-up than is given by earlier

types of MCBs.

Lifeline Range: RCDs – Technical Data

OPERATION

The RCD employs the current balance principle which involves the

supply conductors to the load (phase and neutral) being wound onto a

common transformer core to form the primary windings.

Under healthy circuit conditions, the current in the phase conductor is

equal to the current in the neutral, and the vector sum of the current

is 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 the

transformer and at a pre-determined level of out of balance will

activate the trip mechanism.

Single phase and neutral or three phase and neutral units (suitable for

3 or 4 wire systems) are available, the latter being suitable for balanced

or unbalanced 3 phase loads.

The RCD trip mechanism will operate at a residual current of between

50–100% of its rating tripping current (sensitivity).

TRANSIENT EARTH LEAKAGE CURRENTS

All Wylex residual current devices incorporate a high level of immunity

to tripping when subjected to transient earth leakage currents.

Such transients can occur when there is a significant level of

capacitance to earth as can result from cable capacitance (particularly

MICC) or RF filter networks. Wylex RCDs are therefore less

susceptible to nuisance tripping due to transient earth leakage

currents.

RESIDUAL TRIPPING CURRENTS

10mA

Used in special applications where additional protection against contact

is essential due to the nature of the installation.

30mA

Tripping current designated by the IEE Wiring Regulations to provide

additional protection against direct contact shock, ie socket outside

the equipotential zone. TT systems, caravan installation, etc.

100mA

Suitable for use against indirect contact shock or where protection is

provided to guard against firehazard, etc, rather than to provide

additional protection to personnel, and where the earthing

requirements need supplementing by RCD protection.

100mA time delay

Suitable for use when total RCD protection is required to supplement

the system earthing and where local 30mA RCDs are used to give

additional protection against direct contact. The time delay RCD will

discriminate with the 30mA RCD.

300mA

For use in large installations where plant and equipment protection are

the main considerations and high levels of earth leakage are

experienced.

APPLICATION GUIDE FOR RESIDUAL CURRENT DEVICES

A test button is provided on all RCDs to enable the operation of the

device to be checked.

It is recommended that an RCD is tested regularly.

4In 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 used

throughout industry, commerce and in the home. Typically, the purpose

of these semi-conductor devices is for monitoring and controlling

industrial equipment, eg speed controls for small motors and

temperature controls, along with extensive use in computers, VDUs,

printers, washing machines, etc.

As the equipment is fed from the mains electrical supply, in the event

of an earth fault the presence of semi-conductors may result in the

normal ac waveform being replaced by a non-sinusoidal fault current. In

some cases the waveform may be rectified or chopped. These

waveforms are said to contain a pulsating dc component which can

either 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 AC

RCDs for which tripping is ensured for residual sinusoidal alternating

currents, whether suddenly applied or slowly arising.

Type A

RCDs for which tripping is ensured for residual sinusoidal alternating

currents and residual pulsating direct currents, whether suddenly

applied or slowly arising.

To ensure the correct level of protection, check for the following

symbols:

Protection. (IP3X)

CONSTRUCTION

Wylex NH MCB distribution board

enclosures are fabricated in heavy gauge steel

and are rust protected and highly resistant to

both weathering and mechanical damage.

Incorporated in the distribution boards are

multi-terminal dual earth and neutral bars.

They are designed for ease of installation and

have ample wiring space.

The WYLEX PSB miniature circuit breakers

are rated at 10kA and are of the fault limiting

type.

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) keeping additional damage

at the point of the fault to a minimum.

Additionally this allows discrimination with

HRC fuses at high fault levels.
