Arc suppression circuits
Arc Suppression Circuit Calculation Explained. How arc suppression works. 1. When the contacts in an arc suppression circuit open, the applied voltage is placed across the capacitor and not the contacts. 2. The capacitor charges at a rate faster than the contacts open which prevents an arc from forming across the contacts. 3.

Snubber Circuits for Protecting Relay Contacts from Arcing
I used to work for a company that made motor protection systems that were used in petrol pumps. They used a 0,1uF X2 400vac capacitor in series with a 100R 0,25W carbon film resister across all the motor relay contacts. As this is a potentially explosive environment the devices required BASEEFA certification.
