Miniature Circuit Breaker
Electrical Distribution needs are continuously
evolving in residential, commercial and industrial
sectors. Improved operational safety, continuity
of service, greater convenience and operating
cost have assumed a tremendous significance.
Miniature Circuit Breakers have been designed to
continuously adapt to these changing needs.

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.

Mini MCB
Havells Mini MCB is a single composite device,
which provides, protection against overload
and short circuit faults. It is designed with
unique mounting concept, for use in domestic
& commercial distribution systems, at the most
downstream circuit (switchboards / DESB),
ensuring even higher degree of protection for
discriminating applications.
In normal operation, this new Mini MCB is safe to
use & there is no threat to user and environment.

Mini MCB
Havells Mini MCB is a single composite device,
which provides, protection against overload
and short circuit faults. It is designed with
unique mounting concept, for use in domestic
& commercial distribution systems, at the most
downstream circuit (switchboards / DESB),
ensuring even higher degree of protection for
discriminating applications.
In normal operation, this new Mini MCB is safe to
use & there is no threat to user and environment.
