ded Case Circuit Breaker
nnnnGM1
nnnnApplication
nnnnGMl(CMl) series moulded case circuit breaker is applicable to the circuit of AC 50/60Hz,
nnnnrated insulation voltage SOOV,rated opertating voltage up toAC 600V or 250V(DC),rated
nnnnoperating currnet 6A-S00A.It can be used in motors for unfrequent starting and interruption
nnnnwith the function of the protection against overload,short circuit and undervolatge and
nnnncapable of preventing damage of circuits and supply units due to its protection devices
nnnnfor over-current,short circuit and undervoltage.The MCCB complies with standard of
nnnnIEC60497-2&GB1404S-2.According to its limit short circuit breaking capacity(lcu),the breaker
nnnnare classified into C-type(economical type with current trip-release on N pole closing and
nnnnopening with the other three poles),L-type(standard type),M-type(middle high breaking capacity
nnnntype) and H-type(high breaking capacity type).

Tripping characteristic
nnnnThe thermodynamic ralease of the breaker provides the feature of inverse time-delay,
nnnnwhile the magnetic ralease is the instantaneous operation sa shown on table
nnnn(distribution circuit breaker)and table 2(motor protection circuit breakers).
