An Arc Suppression Relay (ASR) is a protective device designed to minimize or eliminate electric arcs that occur during the switching operations of electrical circuits. An electric arc happens when a current passes through an air gap between contacts, often when the circuit is opened. While an arc is a natural occurrence in high-voltage systems, it can cause damage to components, pose a fire risk, and lead to potential system failures. The primary role of the ASR is to suppress this arc formation or reduce its intensity to protect the circuit and enhance safety.
