SNUBBER - RC device to reduce EMI/RFI across contactor coils for using radio controls or plc's on electrical panels etc.

The R-C Snubber is intended to suppress the “inductive kickback” from  relay coils or devices that create an electromagnetic collapsing field. High energy noise spikes are generated whenever current is interrupted through an inductive load connected to a switching circuit. These electromagnetic noise spikes (EMI) may interfere with electronics equipment causing erratic operation, CPU failure and may also accelerate relay contact wear. Typically this helps to protect radio controls from spikes on the control lines across contactor or relay coils. Applied across an inductive load, the R-C snubber suppresses the electrical noise spikes to electronics and extends contact life on mechanical relays.
