DC Circuit Breaker - 2P, 250A, 500VDC (NV821389)

Molded case DC circuit breaker 2Pole, 250A, 500V
 Features: Molded case circuit breaker for solar PV battery energy storage systems (BESS) and UPS application. Suitable for charge and discharge without connect direction limit (non polarity design). The BESS systems including batteries requires reliable and safety protection and isolating devices.  Moulded case circuit breaker is mainly used in large solar power system, which are applied for DC combiner box, inverter and DC power distribution cabinet. The BDM breaker is designed for applications including solar photovoltaic, electric vehicle charging stations, commercial battery storage and UPS applications. For DC circuit over-current protection and controlling. Can be used in grounded or ungrounded systems. Meets IEC standards for protecting and isolating DC circuits up to 500V and 250A rated operating current. Can be applied in grounded or ungrounded systems. Protection agains: overload, short circuit, unfrequent operation. Tested in extreme environmental conditions from -40°C to 85°C.
