• Multi-scenario application

ZW series pole-mounted vacuum circuit breakers meet the new requirements of the State Grid for the integration of primary and secondary pole-mounted switches. The various functional modules of the circuit breaker are highly integrated. The high-precision AC sensor, power supply module, and vacuum arc extinguishing chamber are integrated and sealed in the pole of the circuit breaker body. Arc extinguishing, voltage and current signal acquisition, and power supply are integrated into one, realizing the deep integration of primary and secondary.
