Product Overview
M1 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 800V and used for circuit of A.C.50/60 Hz rated operating voltage AC 400V(or below), rated operating current up to 1600A for infrequent changing over and starting of the motors. Equiped with the protection devices for over-current, short circuit and under voltagethe products are capable of preventing damage of circuits and supply units. The products conforms to GB14048.2, IEC60947-2 stardands.
Classfication of MCCB
According to product poles, two kinds of three- pole and four-pole are provided. The neutral pole(N pole) of four pole has four types:
Type A: No current trip-release on N pole which making all the time; not closing and opening with the other three poles.
Type B: No current trip-release on N pole which closing and opening with the other three poles.
Type C: With current trip-release on N pole which closing and opening with the other three poles.
Type D: With current trip-release on N pole which making all the time; not closing and opening with the other three poles.
