RV5/133 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 50 ... 133V AC 50/60Hz or with a DC-operated conventional contactor for a control circuit rated voltage between 50 ... 133VDC.
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.
