Abstract
The moving contact travel behavior influenced the interrupting capacity of a circuit breaker.This paper presents a new modified method to control the operating characteristic for permanent magnet(PM) type circuit breaker.The travel curve of moving contact can be controlled by controlling the current in open and close coil.The result of laboratory tests and the availability are presented.
