VS1, ZN63-12KV Side Installation Type Indoor High Voltage Vacuum Circuit Breaker

ZN63(VS1)-12 type Side installation indoor high voltage vacuum circuit breaker is Indoor high voltage switchgear, Applies to rated voltage 12kv, frequency 50Hz three-phase power system,Electrical protection and control as the use of vacuum circuit breaker as a result of the special advantages, in particular the need for frequent operation under the rated current or short-circuit current breaking many places.

ZN63(VS1)-12 type Side installation indoor high voltage vacuum circuit breaker using fixed installation, the main switchboard for the fixed, the circuit breaker can be used alone, but also for the ring network power supply, box-type variable, or a variety of non-standard power supply system.

The use of environmental conditions:

1.Ambient temperature: not higher than +40 °C, not less than -15°C(at -30 °C to allow storage and transportation).

2. Altitude: not exceed 1000m.

3. Relative humidity: daily average of not more than 90%, month average of not more than 90%.

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.
