Vacuum Circuit Breaker

  VD4 Indoor Medium Voltage 12KV Vacuum Circuit Breaker.
- Application: 12kV power distribution system for control and protection.
- Rated current: 630A, 1250A, 1600A
- Rated short-circuit breaking current: 20kA, 25kA, 31.5kA.
- Type: handcart drawable type & fixed type.
- Advanced arc-extinguishing mode adopted. - High insulation level and peak withstand current capacity. - Impact and vibration reduced, Less maintenance.

    Vacuum circuit breakers, which used vacuum as an arc extinction medium. In this circuit breaker, the fixed and moving contact is enclosed in a permanently sealed vacuum interrupter. The arc is extinct as the contacts are separated in high vacuum. The series of products are mainly used for medium voltage ranging from 10 KV to 40.5 KV. 

HT indoor high voltage vacuum circuit breaker(VD4 type) is the indoor switch device for three-phase AC 50Hz, rated voltage 12kA power system, and can be used for electrical equipment control and protection in power plant, substation and industrial and mining enterprises.

Advantages of Vacuum Circuit Breaker

Vacuum circuit breaker does not require any additional filling of oil or gas. They do not need periodic refilling.Rapid recovery of high dielectric strength on current interruptions that only a half cycle or less arcing occurs after proper contact separation.
Breaker unit is compact and self-contained. It can be installed in any required orientation.
