Product Description

      ZN63(VS1)-12  Indoor high voltage vacuum circuit breaker
(Hand cart style)

    ZN63 (VS1)-12 series indoor handcart type high-voltage vacuum circuit breaker is a three-phase AC 50Hz, rated voltage of 12kV indoor switchgear, which can be used for the control and protection of industrial and mining enterprises, power plants and substations, electrical facilities, and is suitable for frequent operation places. The operating mechanism is integrated with the circuit breaker body, and the design can be used as a fixed installation unit, or it can be equipped with a special propulsion mechanism to form a handcart unit. The main circuit part can be used as an integral solid pole to achieve circuit breaker miniaturization, high reliability, maintenance-free, can be equipped with KYN28A-12 (GZS) and other mid-mounted handcart switchgear, fixed can also be used for XGN series fixed switchgear.
 

ZN63(VS1)-12 Side mounted indoor high voltage vacuum circuit breaker
(Side-mounted)

    ZN63 (VS1)-12 side-mounted indoor high-voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is suitable for indoor switchgear of 12kV power system, as a power grid equipment, protection and control unit of power design of industrial and mining enterprises, suitable for switching loads of different properties and frequent operation, multiple breaking short-circuit current occasions. The product adopts a new type of circuit breaker operating mechanism, and the VSC primary part can be fixed with an international brand pole, which seals the vacuum interrupter and the main electrical circuit parts into a whole, protects the arc extinguisher from the impact of collision, dust and condensation, has strong environmental adaptability, greatly reduces the operation and maintenance costs, and truly realizes the primary partial maintenance-free product and less maintenance of the operating mechanism; The integrated design of the operating mechanism and the circuit breaker body has been verified by type test; It has E2 electrical life and M12 mechanical life.
