Vacuum circuit breaker VSC-12 side-mounted miniaturized indoor high-voltage from Hubei JUCRO Electric

Vacuum Circuit Breaker accept customized order according to technical drawing or samples.

VSC-12 side-mounted miniaturized indoor high-voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is suitable for indoor switchgear of 12KV power system. It is used as protection and control unit for power grid equipment and industrial and mining enterprise power design. A variety of different types of load and frequent operation, multiple times to open short-circuit current. The product adopts the new circuit breaker operating mechanism. The VSC can use the international brand solid-sealed pole in one part, and the vacuum interrupter and the main conductive circuit parts are solidly sealed to protect the arc chamber from collision, dust and condensation. Impact, strong environmental adaptability, greatly reducing the operation and maintenance costs, truly achieving one-time maintenance-free operation of the product, less maintenance of the operating mechanism; integrated design of the operating mechanism and circuit breaker, verified by type test; with E2 electrical life , M12 mechanical life.

Normal use environment:

Ambient temperature: maximum temperature +40 ° C, minimum temperature -25 ° C.

Ambient humidity: daily average relative humidity ≤ 95%, monthly average relative humidity ≤ 90%, daily average vapor pressure ≤ 2.0 * 10-3MPa, monthly average vapor pressure ≤ 1.8 * 10-3MPa

Altitude: no more than 1000mm.

The seismic intensity does not exceed 8 degrees.

The surrounding air is not significantly contaminated by dust, smoke, corrosive or flammable gases, vapors or salt spray.

Note: Exceeding the requirements of the above normal use environment conditions, it is necessary to negotiate with the factory.
