CM1 series moulded case circuit breaker is one of products developed and manufactured by adopting international

advanced technology. It is supplied with rated insulating voltage 550 and 800V and used for circuit of AC 50/60Hz,

rated operating voltage AC 400V (or below), rated operating current up to 1600A for infrequent changing over and

starting of the motors.The products conforms to IEC60947-2 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).
