Product Description

1. Application

HM1 series moulded case circuit breaker is one of products developed and manufactured by adopting international advanced technology. It is supplied with rated insulating voltage 500 and 800V and used for the circuit of AC 50/60Hz, rated operating voltage AC 400V (or below), rated operating current up to 1600A for infrequently changing over and starting of the motors. The products conforms to IEC60947-2 standard.

2. Main Technical Specification

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	Rated current(A)	Pole	Rated insulating voltage(V)	Rated operating voltage(V)	Arcing- over distance (mm)	Ultimate short circuit breaking capacity (kA)	Service short circuit breaking capacity (kA)	Operation performance		Utilization cate- gory

Type A: Without current trip-release 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.

1. 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.
