RC type surge suppressor designed to reduce overvoltage surge effects from coil operation

RT5/150 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 77 ...150 V DC. The operation of inductive circuits causes overvoltages, in particular on opening of the contactor coil. The electromagnetic energy stored in the coil during contactor closing is restored on opening in the form of surges, the slope and amplitude of which may rise to several kilovolts. A number of drawbacks are observed ranging from interference on the electronic devices to breakdown of insulators and even destruction of certain sensitive components.Advantages:- the surge suppressor is clipped onto the top or side part in regards with the contactor or contactor relay base design without change in device overall dimensions. - good energy absorption - Unpolarized system - Simple, reliable system- very fast clipping: attenuation of steep fronts and thus of high frequencies. No operating delays.Drawback: a certain delay on drop out which does not however reduce contactor breaking capacity.
