Description
Description

. Function:
MCCB to distribute electric power and protect circuits and equipment against overload,
undervoltage, and short-circuit faults.
MCCB to infrequently start and control AC motors.
MCCB to protect users against indirect contact.
MCCB to protect electrical installations against insulation faults (fire hazard, etc) .
MCCB used in building and factory.
2.Constructional features :
Thermamagnetic release offers instantaneous trip against short-circuit and long time delay trip against overcurrent.
The residual operating current value can be fixed or adjustable.
The residual operating current protection can be with time-delay or without time-delay.
Various accessories can be attached to the circuit breaker to extend its functions, such as undervoltage release, shunt release,ON/OFF position.
