ZW20F-12/T630-20 high-voltage outdoor boundary vacuum circuit breaker is a user boundary switch independently developed by our company. It mainly consists of three parts: ZW20F-12 outdoor vacuum circuit breaker body, "type controller", and external power supply. The three are connected through control cables and have automatic fault detection, protection control, and communication functions. It can reliably detect short circuits, overcurrent, and single-phase grounding faults in the internal and external lines, and automatically relieve faulty lines and equipment.
ZW20F-12/T630-20 high-voltage outdoor boundary vacuum circuit breaker is an outdoor distribution equipment with a rated voltage of 12KV three-phase AC 50HZ. It adopts vacuum breaking and arc extinguishing and SFS gas insulation medium. The box adopts Toshiba's sealing, explosion-proof, and insulation technology, and is filled with zero pressure SFS gas inside, without leakage or external influence. This circuit breaker is a maintenance free, high-performance, and highly reliable new generation vacuum circuit breaker.
ZW20F-12/T630-20 high-voltage outdoor boundary vacuum circuit breaker is mainly used for power lines of 12KV and below,. As a function of line quick break protection, overcurrent protection, grounding protection, disconnection and closing of lines, it is suitable for power grid lines with neutral points not grounded, neutral points grounded through arc suppression coils, and neutral points grounded through low resistance.

Usage environment:
Environmental temperature: -40 ℃ -40 ℃
Altitude: 1000m. For use in high-altitude areas, the external insulation performance needs to be improved
Wind speed: not exceeding 35m/s
Ice covered: Level 10
