Product Description

ZN63 (VS1) -12 indoor high voltage vacuum circuit breaker is a three-phase AC 50Hz, rated voltage of 12kV indoor switchgear, control and protection for industrial and mining enterprises, power plants and substations, electrical facilities, and for frequent operation place. Adopting VET operating mechanism and circuit breaker integrated , design can be used as a fixed installation unit can also be equipped with special advance mechanism, the composition of handcart unit used. Some of the main circuit can use the whole solid seal post, in order to achieve smaller circuit breakers, high reliability, maintenance-free, can be equipped with KYN28A-12 (GZS) and other handcart switch cabinet in the home can also be used with fixed XGN switchgear.

The use of environmental conditions:

1.Ambient temperature: not higher than +40 °C, not less than -10°C (at -30 °C to allow storage and transportation).

2. Altitude: not exceed 1000m.

3. Relative humidity: daily average of not more than 95%,saturated vapor pressure daily average of not more than 2.2 × 10-3MPa, month average not more than 1.8 × 10-3MPa.

4. Earthquake intensity: not more than eight.

5. No fire, explosion hazard, serious filthy, chemical corrosion, as well as places of intense vibration.
