Vacuum circuit breaker VED 12 12KV 1250A 25KA VCB with copper parts 210 mm phase distance
VED-12 series Indoor high voltage vacuum circuit breaker suitable for 12kV air-insulated indoor switchgear, used as a protection and control unit for power equipment of industrial and mining enterprises. Due to its super perfection, it is especially suitable for places where frequent operation is required under rated operating current or multiple rupture under short circuit of rupture current. The circuit breaker adopts the integrated design of the working mechanism and the body of the circuit breaker, servers as not only a fixed installation, but also a type of crossing equipped with a special breakout mechanism.
VED-12 has two main types. One of them is the type of strikeout. Model Number VED-12D. The other is a fixed type.Model Number VED-12F.
