Automatic transfer switch RDCPSS

manualbusbarfor generators

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. 4.Normal opération condition 4.1 - Ambient air temperature:Max +40°C, Min -10°C, day average temperature shall no exceed +35°C. 4.2 - Altitude: up to 2000m. 4.3 - Humidity: Max relative humidity shall not exceed 50% at +40°C, and the higher humidity is acceptable under lower temperature,for instance,it can reach 90% at +20°C.And the condensation caused by temperature change shall be taken care. 4.4 - Protect level:IP 20, Anti touch finger function 4.5 - Pollution level:3 level 4.6 - Install type: Main circuit 380V for IV,Auxiliary circuit and control circuit for III, Alarm circuit for II.
