RC5-1/440 is an RC 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 nominal control voltage between 250 ... 440 V AC 50/60Hz.
Advantages:

• The surge protector is snapped onto the top or side of the contactor or auxiliary contactor without changing the dimensions of the device.
• Very fast clipping: attenuation of steep fronts and therefore of high frequencies. No operating delays.
