Product features:

Main circuit

? The vacuum switch tube adopts products of domestic well-known manufacturers. They have matured technology, reliable quality and good market credit.

? It has fully insulated modular architecture, with unique, reasonable & compact structure, elegant appearance and small size.The unique structure design is easy to form mono polar, dipolar, tripolar and multipolar products。

? The running end has more reliable connections, large conductive cross-section and low contact resistance

? The main circuit is optimized for usage in 2kV voltage, the power frequency withstand voltage can achieve up to 7kV, it can safely replace the old products for usage。

Electromagnetic system

? With unique built-in large capacity sealed auxiliary switch among similar products, this can greatly improve the reliability of the auxiliary switch and it can be used safely。?

? It can optimize the movement structure, reduce the coil starting power and holding power, thus it has low temperature rise, long service life and high reliability。

? Limit buffers are set at moving armature brake-opening limit positions, Eliminating the potential accident hazards due to too large opening rebound amplitude。

Movement structure

? The spindle support is flexible, the load-carrying capability is seizure-free, Axial movement is small, thus the movement performance and consistency are improved。

? The reasonable action mechanism ensures coaxiality of the conductive electric pole during axial movement. This improves the performance and reliability of the breaker。

? It has enhanced the contact pressure of the main contact and improved electrical properties and movement characteristics. The indexes are superior to other similar products。

Easy use and maintenance

? The secondary circuit terminal has functional flags, the wiring is classified by fixed colors to avoid wiring error and make it convenient for wiring. Terminal position can be set according to users' requirements. Number of auxiliary contacts can be combined according to the usage requirements。
