CONSTRUCTION
Miniature Circuit Breakers have precisely formed moulded case & cover of flame retardant high strength thermo-plastic material having high melting
point, low water absorption, high dielectric strength and temperature with stand.
The Switching Mechanism is independent, manual and trip free, i.e., the breaker trips internally even if the operating knob is held in ON position.
The Contact Mechanism comprises of fixed & moving contacts specially designed for reliability, long life and anti-weld properties.
The Arc Extinguishing Device comprises of 15 plates arc chute. The arc under the influence of the magnetic field and arc guide is moved into the
arc chute where it is rapidly split and quenched.
The tripping mechanism is Thermal Magnetic Type.
Thermal Operation
The thermal operation provides protection from moderate overloads. Under overload condition, a thermo-metallic element (bimetallic strip) deflects
until it operates a latching mechanism allowing the main contacts to open.
Magnetic Operation
In magnetic operation, large overloads or short circuit current actuates a solenoid causing a plunger to strike the latching mechanism rapidly opening
the main contacts.

TRIPPING CHARACTERISTICS
Based on the Tripping Characteristics, MCBs are available in ‘B’, ‘C’ and ‘D’ curve to suit different types of applications.
‘B’ Curve: for protection of electrical circuits with equipment that does not cause surge current (lighting and distribution circuits). Short circuit release is set to
(3 - 5) In
‘C’ Curve: for protection of electrical circuits with equipment that causes surge current (inductive loads and motor circuits).
Short circuit release is set to (5 - 10) In
‘D’ Curve: for protection of electrical circuits which causes high inrush current, typically 12-15 times the thermal rated current (transformers, X-ray machines
etc.) Short circuit release is set to (10 - 20) In
CURRENT LIMITING DESIGN
In a current limiting breaker, the tripping & arc control mechanism are so designed that
under short circuit conditions, the contacts are physically separated and the
electrodynamic forces set up by fault current, assist the extinction in less than half
cycle.
The figure shows the current limiting effect of circuit breakers.

HAMMER TRIP MECHANISM
Current Limiting design in itself may not fulfill the requirement of quick breaking
(instantaneous action) mainly due to inertia of the Latch mechanism and
interconnected sequence of operations.
A Hammer directly connected to the plunger strikes the moving contact arm
with a force proportional to the peak current there by forcibly separating the
moving contact from the fixed contact much before the latch mechanism
operates. This further reduces the opening time of the circuit breaker.

EFFECT OF FREQUENCY VARIATION
MCBs are designed to operate at AC frequency 50 / 60 Hz. However, MCBs specially suitable for DC applications and for frequencies upto 400Hz can be
supplied on request.
These can be used on different frequencies in supply from 16 2/ 3 - 60 Hz without any deration.
For higher frequencies, normal MCBs can be used with a multiplication factor which shall only affect its magnetic trip current.

DC APPLICATION
MCBs for DC application are specially designed to meet tough arc quenching
conditions. While selecting circuit breaker for DC applications following parameters
have to be taken into consideration.
Normal Circuit Currents
The rating and normal running temperature of the MCB are unaffected by DC. The MCB
can be selected using the thermal section of the standard time / current curves .
Magnetic tripping on DC is different from the equivalent AC by a peak factor of 1.4
ie., for ‘B’ curve AC MCB, magnetic range
= (3-5) ln
for DC MCB, magnetic range
= 1.4(3-5)ln = (4-7)ln
for ‘C’ curve AC MCB, magnetic range
= (5-10)ln
for DC MCB, magnetic range
= 1.4(5-10)ln =(7-14)ln
Short Circuit Currents
The maximum short circuit current possible on a DC system is determined
by the voltage of the battery and the total internal resistance of the cells.
It is given by Ohm’s law :
Isc =
Vb
Rb
Where, Isc is the Short Circuit Current
Vb is the voltage of the battery (with 100% charged battery)
Rb is the internal resistance of the battery cells
(this is usually stated by the manufacturer)
Circuit Time Constant
L
The time constant is given by : R
where L is the inductance of the circuit
R is the resistance of the circuit
The time constant is usually given in milliseconds (ms.). Ideally, DC circuits would be mainly resistive (i.e. a low number), as inductive circuits produce a back
emf when the current suddenly falls. This in turn tends to prolong arcing during switching operations, and so reduce contact life.
Circuit Voltage
The voltage of the circuit is dependent upon the power supply. The lower the voltage the easier switching operations will be, but the voltage makes no difference
to the running of the MCBs.
Contact life can be significantly increased by reducing the voltage, drop accross each pole. This can be achieved by wiring poles in series.
MCBs have been successfully tested on DC and can be used under the following conditions :

Changeover Switch
MCB Changeover switch finds wide & varied
applications in industries as well as in domestic
sphere for use in low voltage distribution circuits,
wherever continuity of supply is necessary, for
switching to an alternate source of supply from
main supply and vice - versa.
They are switch disconnectors with independent
manual operation, capable of making, carrying
and breaking currents under normal circuit
conditions, which may include operating
overload condition and also carry currents under
specified abnormal circuit conditions such as
those of short circuit for a specified time.

Residual Current Circuit Breaker
(RCCB) 16A - 63A
The flow of current through electrical facilities
always involves risks. Poorly insulated
equipment, faulty wires and incorrect use of an
electrical device cause currents to flow through
the wrong path (i.e. through the insulation) to the
earth. This current is called ‘Leakage Current’.
Earth leakage is an electrical hazard and is
responsible for electrical shocks and fire risk.
Earth leakage and its associated hazard can be
prevented by Residual Current Circuit Breaker
(RCCB), also popularly known as Earth Leakage
Circuit Breaker (ELCB).

PROTECTION
AGAINST ELECTROCUTION
The use of exposed, substandard, badly wired, wrongly connected or damaged equipment as well as frayed or badly repaired cables reduces the safety of an
installation and increases the risk of person receiving an electric shock.
Electrocution is a passage of current through human body, which is dangerous. The flow of current through human body effects vital functions.
1.
Breathing
2.
Heartbeat
A correctly chosen RCCB can detect small currents flowing to earth and reduces the risk of electrocution. Effect of electric current through human body has
been well researched and following chart summarizes the results:
Effect of electric current through human body has been well researched and following chart summarizes the results:
500 mA
Immediate cardiac arrest resulting in death
70-100 mA
Cardiac fibrillation; the heart begins to vibrate and no longer beats at a steady rate.
This situation is dangerous since it is irreversible
20-30 mA
Muscle contraction can cause respiratory paralysis
10 mA
Muscle contraction : the person remains “stuck” to the conductor
1-10 mA
Prickling sensations
However, electrocution should not be viewed in terms of “current” alone, but in terms of “contact voltage”. A person gets electrocuted by coming in contact with
an object that has a different potential from his/her own. The difference in potential causes the current to flow through the body.
The human body has known limits:
-
Under normal dry conditions, voltage limit = 50V
-
In damp surroundings, voltage limit = 25V
AGAINST INDIRECT CONTACT
Over current protection devices like MCB are unable to act promptly on small earth leakage currents. To comply with wiring regulations, the earth fault loop
impedance in Ohms, multiplied by the rated tripping current of the RCD in amperes must not exceed 50.
Example
For an RCD with a rated tripping current of 30mA, the maximum permissible earth fault loop impedance is calculated as follows: Zs (max) = 50 / In
= 50/0.03 = 1,666

AGAINST FIRE
The majority of fires which occur as a result of faulty wiring are started by current flowing to earth. Fire can be started by fault current of less
than 1 amp.
The normal domestic overload protective device such as a fuse or MCB will not detect such a small current. A correctly chosen RCD will detect
this fault current and interrupt the supply, hence, reducing the risk of a fire starting.

WORKING PRINCIPLE
The RCCB works on the current balance principle. The supply conductors, i.e. the phases
and the neutral, are passed through a torroid and form the primary windings of a current
transformer. Its secondary winding is connected to a highly sensitive electromagnetic trip relay,
which operates the trip mechanism.
In a healthy circuit, sum of the currents in phases, is equal to the current in the neutral and
the vector sum of all currents is equal to zero. If there is any insulation fault in the current and
leakage current flows to earth, the currents do not balance and their vector sum is not equal
to zero. This imbalance is detected by the core balanced current transformer, the RCCB is
tripped and supply to load is interrupted. The trip mechanism is operated at a residual current
between 50-100% of its rated tripping current.
39
RES IDU A L C U RREN T C IRC U IT B R EAKER
SELECTION
30 mA
A 30 mA ELCB will provide a high degree of protection against electrocution in an accidental shock hazard situation. The current flowing through human body
could be between 80mA and 240mA depending on the resistance of the human body and the voltage across it.
Zone
Physiological Effects
Zone 1
Usually no reactions
Zone 2
Usually no harmful physiological effects
Zone 3
Usually no organic damage to be expected. Likelihood of muscular
contraction and difficulty in breathing, reversible disturbances of formation
and conduction of impulse in the heart and transient cardiac arrest without
ventricular fibrillation increases with current magnitude and time.
Zone 4
In addition to the effects of Zone 3, probability if ventricular fabriliation
increased upto 5% (curve C2) upto 50% (curve C3) and above 50% beyond
curve C3. It increases with magnitude and time, and pathophysiological
effects such as cardiac arrest, breathing arrest and heavy burns may
occur.
To be within zone of the IEC curve as shown above. It is necessary for the ELCB to operate within 50ms at 240 mA and 150ms at 80mA. Both these conditions
are satisfied by 30mA ELCB.
For households, individual outlets, wet areas and temporary installations, ELCB with sensitivity not exceeding 30mA is advisable.
100 mA
A 100mA ELCB will normally give high degree of protection against electrocution but there is a possibility that the shock current could fall below the tripping level
of ELCB. This could occur if additional resistances to that of human body are included in the earth path.
The 100mA RCCB protects against leakage currents and indirect contact with earth loop impedance upto 500 Ohms.
300 / 500mA
A 300/500 mA ELCB may be used where only fire protection is required. eg., on lighting circuits, where the risk of electric shock is small. 300/500mA ELCB
will not give any protection against electrocution.

Havells new RCBO is a single composite device which provides protection against over currents and earth leakage faults in the same width and profile as that
of a standard MCB. It is designed for use in domestic, commercial and industrial distribution systems at the most downstream circuit for ensuring high degree
of protection to the user for a particular circuit. In normal use, it is safe to use and poses no threat to user as well as to environment.
FEATURES
z
Positive contact indication: Red for ON , Green for OFF
z
Short circuit breaking capacity 10 kA.
z
Large terminal capacity: RCBOs have 35 mm2 for cool running while in operation.
z
Protection in case of loss of supply neutral: Even in event of loss of supply neutral, Havells RCBO provides protection against earth faults . The Functional
Earth (FE) white color wire connected to earth provides this protection.
z
Controlled response & immunity to nuisance tripping: The trip level and the response time of the Havells VD (Voltage Dependent) RCBO using electronic
circuit is set to very precise values and thereby provide greater immunity to nuisance tripping that can be caused by mains borne noise, surge voltages,
lighting surges, reactive loads, mains filters, etc.
z
Neutral to earth faults: A connection that occurs between N and E on the load side of any RCBO will impact on its performance and cause the trip level
to increase. In the case of a N - E fault, the user may have no way of knowing that this fault exists and that the RCBO has been desensitised. Under this
condition, the Havells VD RCBO provides a far greater level of protection than a normal VI (Voltage Independent) RCBO.
Aesthetics & Convenience
z
The new module’s unique compact construction enables far more devices to be fitted into a distribution board than previously possible, and 2 Module
RCBO can simply replace existing MCB 2 pole when upgrading a board.
z
High stacking density = smaller chasis & distribution boards.
Reliability & continuity of service
z
Enhanced discrimination with Havells MCBs
z
Back up to 10 kA with BS & DIN fuses
z
Retrofits Havells MCBs in distribution boards with no modifications in general
z
Robust construction.
Energy limiting
Havells RCBO meets the requirements for energy let through by IEC & British Standard for energy limiting class 3.
ADDITIONAL RANGE - TYPE A & S
Type A - Pulsating DC Protection: Any electrical appliance with power control has the ability to produce earth fault currents with pulsating DC (rectified AC)
components. RCBOs that provide this type of protection are referred to as Type A RCBOs.
Standard VI RCBOs do not provide this protection, and are referred to as Type AC RCBOs. Havells VD RCBOs have been specifically designed to provide
protection against pulsating DC fault currents.
z
Type S- Selective or Time Delay: RCBOs are also divided into two categories determined by their response time to an earth fault current, as follows
z
General Type - having a trip time<300mS for fault currents of IDn and < 40ms for fault currents > 5IDn.
z
S Type- having a trip time of 150 - 500mS for IDn, and 40 - 130mS for >5IDn.
(IDn is the rated residual operating current of the RCBO)
As the name implies, general types are intended for general purpose use. However, S (selective) types are normally used in conjunction with downstream general
type RCBOs.
The S type effectively provides discrimination in terms of the response time to earth fault currents for upstream ad downstream RCBOs. For example, when two
RCBOs are connected in series the first RCBO will often be an S type.

Distribution Board DB
Electrical energy has brought along with it a
lot of conveniences, beyond imagination. It’s
consumption has increased manifold be it in
domestic, commercial or industrial applications,
there by creating a need for scientific & effective
method of distribution.
The purpose of electrical wiring is to
systematically distribute current. In the process
the system mainly adopts methods to protect
installation and human life from electrical
hazards such as short circuit, overload and
earth leakage.
The electrical wiring is carried out to distribute
current from a single source of supply to various
circuits, such an arrangement is made inside an
enclosure called Distribution Board.
The Distribution Board is not merely an
enclosure but a comprehensive system in itself,
comprising of copper bus bars, brass neutral
links, earth links to facilitate effective distribution
of current. It incorporates safety devices such
as MCBs, ELCBs and Isolators, which serves to
protect the installation.
A wide range of compact, elegant & economical
DBs with unique features, designed &
engineered to provide user safety, convenience
and operational / maintenance advantages are
offered.

IP RATINGS
The IP (Ingress Protection) rating given to an enclosure states the degree of protection it offers by means of two digits. A summary of these is shown below, for
a more detailed defition, see IEC 60529 : 2000, BS EN 60529 : 1992.
First Digit
Protection against solid foreign objects and access to hazardous parts: The first digit covers protection against penetration by solid objects, which includes
hands and tools such as screwdrivers. At the lowest of seven levels, 0, no protection is offered, either of the equipment itself from damage by intrusion or of a
person contacting live or moving parts. At the highest, there shall be no entry of dust.
Second Digit
Protection against ingress of water: The second digit covers the degree of protection against the entry of water, on a progressive scale. For example, number
1 indicates that dripping water shall have no harmful effect, and number 6, that water projected in powerful jets against the enclosure from any direction shall
have no harmful effects.
No Protection

water up to 15° from the vertical
e.g. fingers
Protected against solid objects over 2.5 mm
e.g. tools and wires
Protected against sprays of water up
to 60° from the vertical
Protected against after splashed from

-limited ingress, no harmful deposits
Protected against low pressure jets of
water from all directions
-limited ingress permitted
Totally protected against dust.
Protected against strong jets of water
e.g. for use on ship decks
-limited ingress permitted
The letter X can be used in place of the first or second digit to indicate that tests have either not been made or are not applicable.

CATEGORY OF DUTY
The category of duty defines the basic type of circuit and switching capability of the device, and selection should be made accordingly.
Utilisation Category
Typical Applications
AC20/DC20
Connecting and disconnecting under no-load.
Assumes all switching operations are carried out by other capable devices before this device is operated.
AC21/DC21
Switching of resistive loads including moderate overloads.
Suitable for purely resistive type loads devices can switch 150% of its rated current under fault conditions
AC22/DC22
Switching of mixed resistive / inductive loads, including moderate overloads.
Suitable for mixed resistive / inductive loads. Devices can switch 300% of its rated current under fault conditions.
AC23/DC23
Switching of highly inductive loads.
Devices complying with AC23/DC23 are provided mainly as back-up to other means of switching. e.g. contacts. In the event
of failure of functional devices, an AC23 / DC23 type device can safety interrupt a stalled motor current. Where devices are
the only means of controlling individual motors, they should comply with the requirements of appendix A of the standard.
(IEC 60947-3)
Ue = Rated Operational Voltage
Icu Rated Ultimate Short Circuit
The normal line-to-line voltage of the
Breaking Capacity
system should not exceed (Ue)
The calculated prospective fault current at the
incoming terminals of the circuit breaker should
not exceed (Icu).
Exception: Using back-up protection as
specified by the manufacturer.
Ui = Rated Insulation Voltage
Ics Rated Short-time Withstand Current
The voltage on which the dielectric properties
The maximum level of fault current operation
Ui = 660V
have conventionally been based using tests at
after which further service is assured without
Tested@
high voltage and mains frequency. It is intended
loss of performance.
2500V ac 50Hz
to replace this value with (Uimp)
Uimp = The voltage on which clearance
distances are based.
The value of transient peak voltage the circuit
breaker can withstand from switching surges or
lighting strikes imposed on the supply.
e.g. Uimp = 8kV, Tested @8kV peak with
1.2/50m (ms)S impulse wave
Icw Rated Short-time Withstand Current
Circuit breakers of utilisation category ‘B’ have a
short-time delay allowing time-graded selectivity
between circuit breakers in series.
(Icw) is the current the circuit breaker will
withstand for the maximum short-time delay
time. Preferred times are 0.05, 0.1, 0.25, 0.5
and 1.0 second.
In = Rated Current
The current which the circuit breaker will carry
continuously under specified conditions and
on which the time / current characteristics are
based.
Unless otherwise slated (In) is based on
a reference ambient temperature of 30°
centigrade.
