JCZ1C-12KV Unipolar AC high voltage vacuum contactor is a special purpose model developed according to the market demand by relying on the company's R & D strength and user's many years' actual usage experience. it is the ideal electrical appliance specially suitable for frequent operations

Optimized design has been specially carried out in JCZ1C series for capacitive load, all indexes have been promoted, they can be reliably used in capacitive load switching (make-and-break of transformer bank(AC-6a) and the make-and-break of capacitor bank (AC-6b)).

This series of products mainly consist of vacuum switching tube, actuator, control electromagnet, power module (suitable for AC operating power), as well as other ancillary components, the installation method is horizontal installation.

General product secondary mechanisms use electromagnetic operation mechanisms, the controlling electromagnets realize the closing operation through the actuators. Switching operation is realized by switching spring. We can customize quick closing electric power supply module according to users' needs, or we can use permanent-magnet operating mechanism.

This series of products have good compactness of structure and good insulation property, it also has good maintainability of secondary circuit and it can maintain long term electrical and mechanical life without frequent maintenance.

We welcome the users to choose for usage。

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.

? 630A current grade uses double moving end jointing of end surface and conductive clip, with low resistance, low temperature rise and higher reliability.?

? The main circuit is designed in full accordance with the insulation level specified by the national standard。

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 uses dual-coil electromagnetic system, Coordinating properties in conjunction with actuating force is superior to single coils。?

? 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. In the meantime, the auxiliary switch punches also use the buffer to reduce movement impact and improve the reliability of auxiliary switch。?

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

? Control circuit terminals have function flags for preventing wiring errors. The control terminal block positions can be set according to users' requirements to facilitate wiring. Number of auxiliary contacts can be combined according to the usage requirements。
