Abstract Low-voltage circuit-breaker arc occurs in breaking current process, when the arc sprayed product formation arc-over, arc-over harm, reduce arc-over distance has improved contact and interrupter system structure to improve the arc performance, by eliminating free device suction arc, using the current limiting structure, double breakpoint structure, the vacuum interrupter and other measures.
