Meba Mcb And Mccb HJW-250
·Brief description
G series moulded case circuit breaker not only has compact volume than normal circuit breaker or fuse, but
also supply more advanced performance. Advantages as following:
-Easy installation accessory
-Easy installation accessory
-20A-2500A can equip with electronic trip
-Built in 20A earth fault protection
·Application
HJW-250 is one kind of latest developed molded case circuit breaker in our factory, it is according to cutler-hammer technology, at present we mainly export to South America and Middle East countries, quality is satisfied by our customers.
·Operating mechanism
1.G circuit breaker adopts shaft operation feature, this shaft can instruct circuit breaker’s working condition: ON OFF and PIPPED.
2.When circuit breaker appear overloading, short circuit, shunt or under voltage trip action, shaft will jump to TRIPPED (trip) position, at this time, if need to re-switch on must push shaft to RESET position.
3.On both sides of shaft on EG and RG frame there will have 2 windows, which direct circuit breaker’s working condition, red, green and white each correspondence to: On/OFF/TRIPPED.
