Application

nnnn

GMl(CMl) series moulded case circuit breaker is applicable to the circuit of AC 50/60Hz,

nnnn

rated insulation voltage SOOV,rated opertating voltage up toAC 600V or 250V(DC),rated

nnnn

operating currnet 6A-S00A.It can be used in motors for unfrequent starting and interruption

nnnn

with the function of the protection against overload,short circuit and undervolatge and

nnnn

capable of preventing damage of circuits and supply units due to its protection devices

nnnn

for over-current,short circuit and undervoltage.The MCCB complies with standard of

nnnn

IEC60497-2&GB1404S-2.According to its limit short circuit breaking capacity(lcu),the breaker

nnnn

are classified into C-type(economical type with current trip-release on N pole closing and

nnnn

opening with the other three poles),L-type(standard type),M-type(middle high breaking capacity

nnnn

type) and H-type(high breaking capacity type).

Tripping characteristic

nnnn

The thermodynamic ralease of the breaker provides the feature of inverse time-delay,

nnnn

while the magnetic ralease is the instantaneous operation sa shown on table

nnnn

(distribution circuit breaker)and table 2(motor protection circuit breakers).
