Product Description

A circuit breaker is an automatically operated electrical switch designed to protect an elecal circuit from damage caused by overload or short circuit.

Specifications

It is supplied with rated insulating voltage **0 and **0V and used for circuit of AC *0/*0Hz, rated operating voltage AC **0V

Application

FZM1 series moulded case circuit breaker is one of products developed and manufactured by adopting international advanced technology. It is supplied with rated insulating voltage **0 and **0V and used for circuit of AC *0/*0Hz, rated operating voltage AC **0V (or below), rated operating current up to ***0A for infrequent changing over and starting of the motors.The products conforms to IEC******2 standard.

Note: 6A without thermal protection
The N-pole of four-poles breaker is sited at the right side of the product has four types:
Type A: Without current trip-lease on N pole which making all the time, not closing and opening with the other three poles.
Type B: Without current trip-release on N pole which closing and opening with the other poles.
Type C: With current trip-release which closing and opening with the other three poles.
Type D: With current trip-release which making all the time not closing and opening with the other three poles.

3. Protection Characteristic

The thermodynamic release of a circuit breaker provides the feature of inverse time-delay, while the magnetic release is the instantaneous operation as shown on table 2(distribution circuit breaker) and table 3 (motor protection circuit breaker).
