manualbusbaremergency power supply

RDCPSS series ATSE(hereinafter referred to as RDCPPSS switch) is applied to 2-way power supply system of AC rated frequency 50Hz or 60Hz,rated voltage up to 690V,rate current from 0.4A up to 125A,it would transfer the power supply manually or automatically when the overvoltage, undervoltage,phase-loss is happening for ensure the reliability and safety of post circuit power-supply. RDCPSS switch is equipped with intantaneous characterister of contactor, is applied to emergency power supply. And between the power-grids power-supply transfer,it can realize power-off transfer time Min 50ms to improve stability of power. And CB type CPSS switch can be chosen according to each current protect function such as overload,overcurrent,short-circuit,phase-unbalance.
