MCB DP DC Series

Precise hammer action

A hammer directly connectd 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.

Low power consumption

Consumes less power, thus cost effective and energy saving.

15 Plates Arc Chute for effective arc quenching

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 th arc chute where it is rapidly split and quenched.

Trip free mechanism

A circuit-breaker, the moving contacts of which return to and remain in the open position when the automatic opening operation is initiated after the initiation of the closing operation, even if the closing command is maintained.

Longer electrical life

Desgined for better and longer electrical life.

Wide range availability

available in all current ranges.

Permanent Magnet used for DC Arc Quenching
