The ZW20-12 primary-secondary integrated pole-mounted switch is widely used in the market. It adopts a shared-box structure with high sealing and protection capabilities, featuring vacuum arc extinction and SF6 insulation for excellent breaking performance. It withstands harsh outdoor operating environments and is a maintenance-free vacuum circuit breaker. When paired with a controller, it can achieve protection against overcurrent, short-circuit, and single-phase grounding faults, as well as isolation of faulty areas. It has earned widespread recognition from grid users.
