1. Application

nnnn

GM2(NS) series moulded case circuit breaker is applicable to the circuit of AC 50/60Hz,rated

nnnn

insulation voltage 950V,rated opertating voltage up to AC 690V .rated operating currnet 12.5A

nnnn

-630A.It can be used for power distribution and prodection of electrical equipment in case of

nnnn

overload,short circuit and undervoltage and also for unfrequent switchover of electrical circuits

nnnn

under normal conditions.The MCCB conforms to standard of IEC60497-2&GB1404S-2.According

nnnn

to its limit short circuit breaking capacity(lcu),the breaker are classified into D-type(economical

nnnn

type with overload release on N pole) ,N-type(standard type)and H-type(high breaking capacity

nnnn

type)&L-type(highest breaking capacity type).
