R-C SNUBBER NOISE AND ARC SUPPRESSOR
GENERAL DESCRIPTION
The R-C Snubber 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 may
interfere with associated equipment causing erratic operation and may also
accelerate relay contact wear. Applied across an inductive load, the R-C
snubber suppresses the noise spikes and extends contact life.

APPLICATION
The R-C snubber inductive load suppressor should be applied as shown
below. Placing the suppressor across the contact in many cases can work
as well, but for maximum effect, it is best to place the suppressor directly
across the load. All inductive loads in a system should be suppressed in
this manner to avoid mutual interference. The suppressors are effective in
both AC and DC circuits.
