AM1 series moulded case circuit breaker is one of products developed and manufactured by adopting
international advanced technology. It is supplied with rated insulating voltage 500V 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
conform to IEC60947-2 standard.
The thermodynamic release of a circuit breaker provides the feature of inverse time-delay,
while the magnetic release is the instantaneous operation as shown Technical Specification
(distribution circuit breaker).
