Application

nnnn

GM3 series moulded case circuit breaker is applicable to the curcuit of AC50/60Hz,rated insulation

nnnn

voltage 690V,rated operating voltage up toAC 660V,250V(DC),rated operating current 10A-1600A

nnnn

for power distribution and protection of elelctrical equipment in case of overload,short circuit and

nnnn

under voltage and also for unfrequent switchover of electrical circuits under normal conditions.The

nnnn

MCCB rated current up to 400A can be used in motors for unfrequent starting and interruption and

nnnn

for protection of motors against overlad,short circuit and undervoltage.The MCCB conmplies with

nnnn

standard of IEC60947.According to its limit short circuit breakeing capacity (lcu),the breaker is

nnnn

classified into N-type(normal function type),S-type(standard function type)and H-type(high

nnnn

function type).
