RT5/90 is a transil diode 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 or with a DC operated conventional contactor for a rated control circuit voltage between 50 ... 90 V DC. The operation of inductive circuits causes overvoltages, in particular on opening of...
