Product Introduction
The circuit breaker tester is a precision device designed specifically for evaluating circuit breaker performance. The device works based on current detection and electromagnetic induction, and monitors current changes in the circuit in real time through built-in sensors. When the current is abnormal, the tester quickly captures and processes these signals to accurately evaluate key performance parameters of the circuit breaker, such as opening and closing time, speed, and operating current.
