Automatic circuit breaker tester UPA-10 is designed for testing and ampere-second characterization of automatic AC current circuit breakers. The device allows registering the value of the supplied current and timing the automatic circuit breaker switching interval.
Primary current injection UPA-10 is a mobile device, which could be easily transported to a required testing location.
