G Series MCCB (G type)

·Brief description
G Series MCCB (G type) not only has compact volume than normal circuit breaker or fuse, but
also supply more advanced performance. Advantages as following:
Easy installation accessory
Common use accessory below 630A
20A-2500A can equip with electronic trip
Built in 20A earth fault protection
· Most reasonable contact terminal system design
Excellent contact terminal design makes G series circuit breaker outstanding performance and high flexibility possible.Our licensed technology adopts speed ‘air-blowing’ system, this system adopts high breaking capacity fault current electric Power.function.
G Series MCCB (G type) adopts operation shaft equipment structure, this structure can trip freely when short circuit, the shaft can direct definitely trip which caused in short circuit or overload, this fast and reliable operation system improve the safety performance.
·Completely testing before delivery
G circuit breaker’s quality and reliable are assured by completely testing, each pole on circuit breaker will make 2 times setting test to assure trip structure, operation structure and continuously and precision.
·Operating mechanism
G Series MCCB (G type) adopts shaft operation feature, this shaft can instruct circuit breaker’s  working condition: ON-OFF and PIPPED.
When circuit breaker appears overloading, short circuit, shunt or under voltage trip action, the shaft will jump to TRIPPED (trip) position, at this time, if need to re-switch on must push shaft to RESET position.
On both sides of the 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.

·Current limit feature

C Series MCCB (G type) adopts high repulsion contact terminal structure and advantage ARC technology, so it has the significant current limits function.
·Standard
IEC60947-1:General rule
IEC60947-2:Circuit breaker
IEC60947-3:Switch, isolating switch, load switch etc.
