12kV Vacuum Circuit Breaker

Product description

Adopting solid seal insulation technology of ABB and SIEMENS. 3AV5-12 indoor voltage vacuum circuit breaker,using epoxy-resin material, immobilizes vacuum interrupter and other parts of primary main circuit to form polar pole with high insulation and mechanical strength, which avoids bad running environment influencing the outside insulation of primary circuit and to get complete maintenance-free. It adopts optimized spring -operation system,with simplified structure and stable performance,which is available for industrial and mining enterprises,power plants as well as electric substation as control and protection of electrical equipment.

3AV5 side-entry vacuum breaker adopts fixed-type installation.It is mainly used for switch cabinet,such as network cabinet,box-type electric substation or all kinds of nonstandard power-supply systems.The main current circuit adopts seal polar pole with small operating plate, which saves space of the cabinet.
