ZN85-40.5/T type indoor high voltage indoor vacuum circuit-breaker is used for switchgear KYN61-40.5(Z), it is most new type of power supply and distribution equipment. This product is accordance with GB1984-2003 stand. This series include: Vacuum circuit breaker truck, isolation truck and fuse truck.

Structural characteristics:

1. This vacuum circuit breaker adopts compound insulation; It can meet air distance and creepage under normal run condition, and it effectively reduces the dimension of VCB, the overall arrangement is reasonable and simple, with aesthetic appearance.

2. The operating mechanism is especially newly designed for this VCB; The outlet curve has good adaptation with requirements of vacuum interrupters. It has high reliable with characteristics of long life and easy maintenance and free-maintenance for operating mechanism.

3. This truck adopts screw rod nut push-in mechanism which can realize easy pushing-in or pushing-out of panel; Compulsive mechanical interlock way is adopted; Meet the Five Preventions function; Suitable for varies site and the working sites which have rigorous run condition.

DZ47 series circuit breaker is used in lighting distribution system or motor distribution system for protecting overload and short-circuit in the system. The product is novel in structure, light in weight, reliable and excellent in performance. It has high breaking capacity, can trip quickly and it's installation uses with guide, it's case and items are adopted with high fire-retardant and shockproof plastics. The product, with long life, is mainly used in AC 50Hz/60Hz single-pole 240V or two, three, four-pole 415V circuit for overload and short-circuit protection as well as for unfrequented on-and-off switching electric equipment and lighting circuit in normal case.

Cc Temperature Fuse(over heat fusible) is a heat protective device that can not restoration. It is applicated in home appliances and the over-heat protective of the industrial equipments, when the temperature around rise to unusual, cc temperature fuse will affect the outer-temperature and then cut off the circuit. Its sealed construction can insure stabilization and credibility of the fusible system, and wonot affected by the scurviness environment such as outer-humidity.

The temperature of the equipment rises unusual, the temperature fuse(overheat type) affectd by the environment tempreture, when the temperature reached the melting point Of the fusion, it will melt. And melted alloy shrink to a ball quickly and then cut off The current.
