Fixed Protection 1250A Engineering Vacuum Circuit Breaker

    Each vacuum tube will have a factory number. After thevacuum tube is produced and stored for 8-12 months, it willbe tested whether there is air leakage and whether thepressure resistance passes the market. Most manufacturerssell it now and will not carry out secondary testing

     The vacuum tube used in zhegui vacuum circuit breakerhas been tested for the second time, and the third time willbe tested after installing the vacuum circuit breaker, so youcan buy it at ease

Vacuum Tuoe Details

    All transformers of this product are made of pure red copper, while ordinaryones are made of copper-clad aluminum. Direct use of copper-cladaluminum is easy to cause great potential safety hazards

Copper isolating knife

    The components used in the vacuum circuit breaker are made of real materials. The thickness of the isolation knife is as high as 2.8mm.The ordinary isolation knife is only 2.0mm. Even various operating handles are made of high-quality materials
