The VIG(C) - 12GD series indoor high - voltage three - position vacuum circuit breaker has excellent electrical and mechanical properties, with a reliable and stable mechanism and a long service life. The main circuit adopts solid - sealed pole technology, which improves the environmental adaptability and insulation reliability of the circuit breaker. Reliable mechanical and electronic properties, as well as extended mechanical and electronic service lives, make maintenance - free operation of the circuit breaker possible. It can be used in 3.6 - 12kV power systems as a protection and control unit for power grid equipment and power design in industrial and mining enterprises. It is suitable for various loads with different properties, frequent operations, and occasions with multiple short - circuit current interruptions. The product is equipped with perfect mechanical and electrical interlocking devices, and has extremely high operational stability and reliability, ensuring the safety of operators and equipment, as well as the safety of electricity use.
Adopts solid - sealed pole technology.
The product adopts a modular design: With a frame structure, it is a high - performance and miniaturized high - voltage electrical product that integrates isolating switches, solid - sealed vacuum circuit breakers, grounding switches, sensors, interlocking mechanisms, and operating mechanisms.
The size of the adapted cabinet is (450 x 1000 x 1800) mm.
Rotary isolating switch with visible break points after opening.
There are forced mechanical interlocks between the isolating switch, circuit breaker, and grounding switch to prevent misoperation.
The circuit breaker adopts a modular operating mechanism, which can be replaced or overhauled independently and has good interchangeability. It can be operated manually, or AC/DC energy storage operation can be selected to realize remote control.
The cabinet door and the grounding switch are designed with a reliable interlocking structure to ensure the safety of operators.

Ambient temperature: -25°C to +40°C.
Relative humidity: Daily average <95%, monthly average <90%.
Altitude: Not higher than 1000m.
Seismic intensity: Not exceeding 8 degrees.
Usage site: No explosion hazard, chemical hazards, severe vibration, or filth.
Conditions for use at altitudes above 1000m
When the altitude exceeds 1000m, the air density will relatively decrease, which will affect the protection coefficient of electrical appliances.
Users must make relevant calculations when selecting switches.
