Meba What Is Mccb CM1
1. CM1 series moulded case circuit breaker is one of our new type products developed and manufactured by adopting international advanced technology.
2.It is supplied with rated insulating voltage 800V and used for circuit of AC 50Hz, rated operating voltage AC 400V. (or below),rated operating current up to 800A for infrequent changing over and starting of the motors.
3.Equiped with the protection devices for over current, short circuit and under voltage, the products are capable of preventing damage of circuits and supply units.
4.The product conforms to GB14048.2, IEC60947-2 standards.
5.The thermodynamic release of a circuit breaker provides the feature of inverse time delay, while the magnetic release is the instantaneous operation as show on table 2 (distribution circuit breaker) and table 3 (motor protection circuit breaker).
