Product Description

Indoor Type Vacuum Circuit Breaker Switch 10KV 12KV 630A 1250A 1600A 2500A 3150A 4000A VCB
ZN63-12(VS1-12)/ VD4-12 high voltage vacuum circuit breaker is the indoor switchgear with 12kV rated voltage, three phase AC 50HZ. It acts as the electrical protective and control device in the power system, especially applicable to locations that need frequent operating in rated current or under repeatedly on/off shortcircuit current.

This breaker was designed as a unit which gathering actuator and circuit breaker main body. It can be used for fixed mounting unit, also can be constituted as a withdrawable unit through outfit dedicated advancing mechanism. Corresponding interlock can be increased to meet the needs of XGN2, GG1A and other fixed cabinets. Simultaneously, it can coordinate with the KYN28A-12(GZS1) middle-arranged manual-driven switchgear or XGN-fixed switchgear as well.

Environment

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

• Altitude: not exceed 1000m.

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

• Earthquake intensity: not more than eight.

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