AM1 Series Moulded Case Circuit Breakers
AM1 series of moulded case circuit breaker is one of our new type products developed and manufactured by adopting international advanced technology. It is supplied with rated insulating voltage 660V and used for circuit of A.C.50Hz, rated operating voltage AC 380V.(or below), rated operating current up to 800A for infrequent over and starting of the motors. Equipment with the protection devices for over-current, short circuit and undervoltage, the products are capazble of preventing damage of circuits and supply units.

Motion 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 breakers).
