MCB 10kA
An MCB operates as an automatic switch that opens in the event of excessive current flowing through the circuit and once the circuit returns to normal, it can be reclosed without any manual replacement.

Miniature Circuit Breakers have precisely formed molded 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 12 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 overload. During a current overload, a thermo-metallic element (bimetallic strip) deflects until it operates a latching mechanism allow the main contacts to open.
MAGNETIC OPERATION
In a magnetic operation, large overloads or short circuit current actuates a solenoid causing a plunger to strike the latching mechanism rapidly opening the main contacts.
