The ABB RC5-1/440 is a RC type surge suppressor designed to reduce the maximum overvoltage peak value and to limit or even completely eliminate the high pre-damping voltage frequencies, when used with an AC operated conventional contactor for a rated control circuit voltage between 250 to 440 V AC 50/60Hz.
It has very fast clipping Operating temperature -20 to +70 °C It has 30.25 x 10.5 x 32.4 mm dimensions
