ABB Stotz-Kontakt RV5/440, quenching element, 1SBN050010R1003

RV5/440 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 250 ... 440V AC 50/60Hz or with a DC-operated conventional contactor for a control circuit rated voltage between 250 ... 440VDC. , 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.
