Short-circuit Breaking Test Of Low-voltage Pole-mounted Circuit Breakers

When conducting short-circuit breaking tests at the Lv Pole Mounted Circuit Breakers test station, testers usually need to adjust the voltage, short-circuit current (effective value), and power factor (cosφ). Once these parameters are set, the circuit breaker's connection current under test conditions is also determined. This process is critical for evaluating the circuit breaker's breaking capacity and reliability.
