What is Arc Interruption Theory?Arc Interruption Theory DefinitionArc interruption theory is defined as the process of stopping electrical arcs that occur when circuit contacts open.Methods of Arc InterruptionThere are two main methods: the high resistance method, which increases resistance to zero current, and the low resistance method, which uses the natural zero point of AC current.Restriking VoltageRestriking voltage is the voltage across breaker contacts at the moment an arc is extinguished
