Circuit Breakers Arc Fault Circuit Breakers ① The diameter of the arc extinguishing chamber of the circuit breaker is small the insulation strength is high the arc is easy to extinguish and the arc extinguishing ability is strong. ② The circuit breaker has a short arcing time and a long electrical life and its rated short-circuit breaking frequency is generally between 20 to 100 times or even higher. After breaking the rated short-circuit breaking current there is still a high insulation level between the dynamic and static contacts. ③ The contact distance and contact stroke of the circuit breaker are small with low operating power good breaking performance stable and reliable electrical life and a mechanical life of over 20000 times with few breaking failures. ④ The circuit breaker is safe to use easy to maintain and does not generate high air pressure due to arcing during the breaking process. Therefore the operation risk is low and the vacuum arc extinguishing chamber does not require maintenance.
