SONTUOEC 2P DC500V ,DC1000V Circuit Breaker 63A to 125A DC MCB for Solar PV System General
Application:
MCB series high breaking miniature circuit breaker has the features of structure advanced, performance reliable, breaking capacity high, appearance elegant and its shell and parts are made of material with impact resistance, strong flame-retardant feature.
It is suitable to power system of 50or 60 frequency ,Ue 400V and below, Ui 63A and below.
It is mainly applied at office building, residence, for lighting , power distribution and overload and short circuit protection of equipment. Normally, it also can be used as the not frequent transfer of power system. It conforms to the standards IEC60898and GB10963.1.
DC MCB supplementary protectors are designed to provide overcurrent protection within appliances or electrical equipment, where a branch circuit protection is already provided or not required. Devices are designed for direct current (DC) control circuit applications.
