ABB Surge Suppressor Unit 90 V Maximum Voltage Rating

The ABB 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 to 90 V DC.

It has high energy absorption
Operating temperature -20 to +70 °C
It has 30.25 x 10.5 x 32.4 mm dimensions
