circuit protection

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
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

CUSTOM BUILT

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

NSB CONSUMER UNIT MCBs

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.

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.

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.

RCBO

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.

Zone Physiological effects
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 and
conduction 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 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:

To ensure the correct level of protection, check for the following
symbols:
TYPE AC
normal ac sensitivity

TYPE A
pulsating dc sensitivity

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.

Wylex RCDs are available as both Type AC and Type A devices.

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.
