Arc Suppressor

Arc suppressors sit across a switched contact and absorb the energy that would otherwise strike an arc as it opens, protecting the contact surfaces and the circuit that shares its supply. Panel builders fit one when a relay or contactor is eroding faster than its duty explains, when arcing has begun interfering with nearby electronics, or when an inductive load has to be switched without punishing the contacts.

 

As an authorized electrical distributor for multiple manufacturers, we stock arc suppressors across competing lines, in a full range of voltage and current ratings, so you can match the contact rating and load the circuit switches, compare ratings brand to brand, and extend contact life instead of replacing the device.
