a) R-C element

Circuit with RC Elements



Fig. Basic circuit diagram: RC element


Advantage: 1) Limit the spike to low levels and also limits dv/dt.
2) Can be used for AC & DC contactor

Note: Very careful selection of resistance & capacitance is required to achieve desired switching time of contactor
