  • Circuit Breaker Definition, Working Principle and Arcing

    Working of an SF6 Circuit Breaker. The production of arc not only delays the current interruption process but it also generates enormous heat. This heat may cause damage to the system or to the breaker itself. Therefore, the main problem in a circuit breaker is to extinguish the arc within the shortest possible time. So that heat generated by it may not reach a dangerous value.
