APPLICATION
M1series 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 ofA.C.50/60Hz, 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 undervoltage, the products are capable of preventing damage of circuits and supply units.
The products conforms to GB14048.2, IEC60947-2 stardands.
TYPES AND MEANINGS
Note:*No code for distribution breakers;"2"represents motor protection circuit breakers.
*No code for direct handle operation;"P"represents electrical operation,and"Z"represents rotary-operated- handles.
*Rated breaking capacity grade of MCCB,C-Economical type L-Stardand type M-Middle high breaking capacity type,H-High breaking capacity type.
CLASSIFICATION 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.
