Circuit Breaker Timing Test Equipment

This Circuit Breaker contact resistance tester is mainly used for testing electrical and mechanical characteristic of high voltage circuit breaker, switch and contactor. It an measure the time parameters (close, open, asynchronous, bounce, pre-insert time) of 12 main contacts and 6 resistive contacts. Measure the co-operate time between 6 main- and auxiliary contacts,he resistance and pre-insert time of 6 resistive contacts.
