product details

  3aj 1-12 indoor high voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is an indoor switchgear used in 12kV power system. As a protection and control unit for power grid equipment and power design of industrial and mining enterprises, it is suitable for switching various kinds of loads and frequently operating and repeatedly breaking short-circuit current.

  The product adopts a new type of circuit breaker operating mechanism, and the primary part of 3aj1-12 can adopt the international brand fixed pole to seal the vacuum interrupter and the electrical circuit parts as a whole, so as to protect the interrupter from collision, dust and condensation. It has strong environmental adaptability, greatly reduces the operation and maintenance costs, realizes the maintenance free primary part of the product and less maintenance of the operating mechanism; The integrated design of operating mechanism and circuit breaker body has been verified by type test. It has E2 level electrical life and M2 level mechanical life. It can be used as fixed installation unit or equipped with special propulsion mechanism to form handcart unit. The fixed circuit breaker can add corresponding interlocking to meet the needs of XGN2, ggia, GGX and other fixed cabinets.

  The opening and closing status of circuit breaker can be viewed through mobile app or computer, and the opening and closing operation of circuit breaker can be controlled remotely to solve the problem of local operation of circuit breaker. It has the ability of high efficiency to deal with emergency power supply and power failure events, at the same time, it can save labor and time, and improve the safety and reliability coefficient of power consumption.
