RV5/50 is a varistor surge protector designed to reduce the maximum surge peak value and to limit or even completely eliminate the high bias frequencies when used with an AC-operated conventional contactor for a control circuit rated voltage between 24 ... 50 V AC 50/60Hz or with a DC-operated conventional contactor for a control circuit rated voltage between 24 ... 50 V DC.
The surge protector is snapped onto the top or side of the contactor or contactor relay without changing the dimensions of the device.
High energy absorption: good attenuation - unpolarized system.
