Dab7-63 Dc Miniature Circuit Breaker
DAB7-63 miniature DC circuit breakers are used for overload and short circuit protection of lines with DC voltage up to 250V and rated current up to 63A, and also for infrequent switching of lines. DC MCB circuit breaker is suitable for communication, PHOTOVOLTAIC system and other DC system applications.
Product Description
Products meet
IEC 60948.2, IEC 60947-2 In line with the EU RoHS environmental requirements, DC circuit breakers have passed CCC and other certification
Application
DAB7-63/1p DC circuit breaker is mainly used for overload and short circuit protection of DC electrical circuits and equipment with rated DC voltage up to and including DC250V and current up to 63A. DC circuit breaker can also be used for solar power generation system, working voltage up to DC250V, can rapidly points off the fault current of DC power distribution system, is an important device to protect the solar power system pv module from reverse current in DC side and AC feedback current of inverter failure caused by damage, ensure the reliable operation of solar photovoltaic power generation systems
