[0002] A circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and close, carry, and interrupt current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their application range. The boundary between high and low voltage is relatively blurred. Generally, circuit breakers above 3kV are referred to as high-voltage electrical appliances.

[0003] Before using a circuit breaker, it needs to be tested on a test bench using testing equipment to ensure that the circuit breaker is working properly. During the test, the circuit of the test equipment is connected to the input and output terminals of the circuit breaker.
