ZXMN-A Simulator Circuit Breaker Device

       ZXMN-A simulator circuit breaker device is mainly used for the whole set of test of relay protection device. The device can simulate the tripping/closing of the circuit breaker during the entire group of tests of the relay protection device, which can reduce the number of switching actions, extend the service life of the circuit breaker, shorten the debugging time, improve the test work efficiency, and avoid the circuit breaker during the entire group of tests Inconvenience caused by repeated switching.

       The ZXMN-A simulator circuit breaker device can cooperate with the relay protection tester produced by our company to perform non-stop power verification on the protection device and improve the reliability of power supply.
