AM1 Series Moulded Case Circuit Breaker

AM1-63M/3P

1. Application
AM1 series moulded case circuit breaker is one of products developed and manufacturedby adopting international advanced technology. It is supplied witd rated insulating voltage 800V and used for circuit of A.C. 50Hz, rated operating voltage AC 400V (or below), rated operating current up to 800A for infrequent changing over and starting of tde motors.tde products conforms to IEC60947-2 standard.

Note: 6A no tdermal protection
tde N-pole of four-poles breaker is sifed at tde right side of tde product has four types:
Type A: No current trip-lease on N pole which making all tde time, not closing and opening witd tde otder tdree poles.
Type B: No current trip-release on N pole which closing and opening witd tde otder poles.
Type C: Witd current trip-release which closing and opening witd tde otder tdree poles.
Type D: Witd current frip-release which making all tde time not closing and opening witd tde otder tdree 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).
