Product Description
Application
1.CJMM1 series moulded case circuit breaker(hereinafter referred to as circuit breaker) is pplicable for AC 50/60HZ power distribution network
circuit with rated insulation voltage of 800V, rated operation voltage of 690V and rated operation current from 10A to 630A, it's used to distribute power and prevent circuit and power supply equipment from damage due to overload, short circuit, under voltage and other faults, it's also used for infrequent start of motor as well as overload, short circuit and under voltage protection
2.This circuit breaker owns advantages of small volume, high breaking capacity, short arcing (or noarcing)etc, it can be equipped with accessories like alarm contact, shunt release, auxiliary contact etc, it's an ideal product for user.
3.The residual current circuit breaker can either be vertically installed (vertical installation) or be horizontally installed (horizontal installation)
The product is in accordance with the standards of IEC60947-2 and Gb140482
Classification
1.By breaking capacity: a standard type(type S) b higher breaking capacity type(type H)
2.By connection mode: a front board connection, b back board connection, c plugin type
3.By operation mode: a direct handle operation, b rotation handle operation,c electrical operation
4.By number of poles: 1P,2P, 3P, 4P
5.By accessory: alarm contact, auxiliary contact, shunt release, under voltage release.
Normal Service Condition
