An Arc Suppression Relay is an electrical device that monitors circuits for the occurrence of electric arcs during switching operations. Arcing occurs when an electric current passes through the air between two conductive points, creating a continuous discharge of electricity. This can happen during circuit interruptions, where the contacts of a switch or circuit breaker begin to separate, leading to a momentary connection between them. The result is a flash of light, high temperature, and significant energy expenditure that can be detrimental to the surrounding components.
