Indoor Vacuum Circuit Breakers

ZN85-40.5 Indoor Vacuum Circuit Breakers is a three-phase AC 50Hz, rated voltage of the 40.5KV indoor unit, wearing special spring 3AV3 agencies. Circuit breaker can be configured in JYN1-40.5 (Z)-away metal-enclosed switchgear can also be configured in KYN61-40.5 (Z)-assembly metal-enclosed switchgear use. 40.5KV device is the best in the circuit breaker.

Technical parameters of this series, breaking a strong ability to move reliable, stable performance, long life, easy to maintain, and no danger of explosion and pollution for the industrial and mining enterprises, power plants and substations for single-bus system, electrical facilities and the protection of control , And frequently apply to the operation of the sites, can also be used to cut the whole group of capacitors and other special occasions.

Integrated circuit breakers and modular design, the overall structure simple and reasonable use of the whole arrangement, the interrupter part of the above, and the interlocking actuator below. 3AV3 exclusive right to use the spring mechanism without the need to adjust, stable and reliable action.

Vacuum arranged in a closed tube insulation, improved insulation performance, and reduce the overall size.
