As the professional manufacturer in China, Comewill would like to provide you high quality ZW43 Series Outdoor Vacuum Circuit Breaker, which especially suitable for scenarios with severe pollution or frequent operation, it is particularly reliable for power grid control and equipment protection.
There is no need to worry about the standards, as they fully comply with IEC62271-100, GB1984 (related standards for AC high-voltage circuit breakers), as well as IEC60694, GB/T11022 (general technical requirements for high-voltage switchgear and control equipment).
Super reliable performance: The customized ZW43 Series Outdoor Vacuum Circuit Breaker is built with a three-pillar structure—vacuum arc-extinguishing chamber connects to the operating mechanism via an insulated pull rod. No shaky parts, just steady operation every time.
Tough & anti-condensation: We use APG tech to cast the arc-extinguishing chamber, main conducting loop, and insulation support into a single epoxy resin piece, then coat it with silicon rubber. It’s strong mechanically and won’t have condensation issues, even in damp spots.
Great spring operating mechanism: The switch comes with a high-performance spring mechanism—simple structure, long mechanical life. You can choose manual or electric mode for energy storage and opening/closing—super flexible.
Optional integrated isolation switch: If you need an isolation switch, we can add ZW43 Series Outdoor Vacuum Circuit Breaker on. No need to buy extra parts separately.
Small, sleek & easy to install: It’s compact, looks modern, and doesn’t weigh much. Moving it around and setting it up on-site is a cinch—no heavy gear needed.
Works for automation & unattended substations: The switch can be fitted with a control terminal interface. Perfect for automated distribution networks and substations that don’t need someone on-site 24/7.
