R-C Snubber Noise and ARC Suppressor The R-C Snubber and ARC suppressor is intended to suppress the "inductive kick" from motors, solenoids or relay coils. High energy noise spikes are generated whenever current is interrupted through an inductive load. These noise spikes interfere with associated equipment causing erratic operation and also accelerate relay contact wear.

The R-C snubber suppresses the noise spikes and extends contact life.
