Pole Circuit Breaker

ZW32-12 series outdoor high-voltage AC vacuum circuit breakers are used in AC 50HZ/rated voltage 12KV three-phase power system, as the function of dividing and closing load current, overload current and short-circuit current. The circuit breaker can be equipped with a reclosing controller that can identify current characteristics and realize multiple automatic reclosing or permanent fault isolation; self-provided PT as a power source, becomes a smart circuit breaker with voltage and current signal output and control; electronic PT provides power It can also complete the three-stage compound protection of overcurrent delay, inrush current delay, and short-circuit quick-break.
