Application
DZ12 series moulded case circuit breaker are mainly applied to AC50Hz,rated current to 63A,single phase 230V and three-phase 400V, It also can be used for overload and short circuit protect. and switching the circuit infrequenly under the normal working conditions.
The products conform to the IEC 60898-1 standard.
Type and meaning
Normal operation and mounting requirements
1.The ambient temp.shuold not be higher than +40 and not lower than -5 and the average temp. of 24 hours shuld not exceed +35.
