Snubber Networks Snubber Networks are easily selectable electronic components designed to prevent or substantially minimize the occurrence of arcing and noise generation in relay and switch contacts.Snubber Networks consist of specially designed capacitors and resistors connected in series.he dielectric material in capacitors, used in Snubber Networks, affords a very high degree of voltage withstand strength. All resistors are non-inductive types to ensure a high degree of protection against pulse potentials.
