PSDX7-63 Miniature DC Circuit Breaker
GENERAL
PSDX7-63Z series DC miniature circuit breaker is used for DC voltage to 1000V, rated current to 63A circuitfor overload and short circuit protection, which can also be used as infrequent operation and transformation. The breaker is suitable for communication, photovoltaic system and other applications, such as DC system. Products comply with: GB 14048.2, IEC 60947-2 European Union RoHS environmental protection requirements Access to CCC, CB certifications
Application
PSDX7-63Z miniature DC circuit breaker is mainly used for DC rated voltage up to 1000V, overload and short circuit protection of current 63A DC electrical circuit and equipment. PSDX7-63Z miniature DC circuit breaker can also be used for the solar energy photovoltaic power generation system, the working voltage can be up to DC 1000V, which can rapidly break the DC fault of DC power distribution system; an important device ofthe solar powersystem - PV module can be protected from the reverse current from DC side and the hazard of feedback current from the AC side due to failure of inverter, to ensure the reliable operation of solar photovoltaic energy system.
