Product synopsis:

?KCC3-24kV  series AC vacuum contactor is the next-generation product developed by the company in response to the market needs, it can completely meet the latest requirements of 20kV network.The company has summarized users' experience through many years and redesigned the original product, therefore, we have remarkably improved the product both in performance indexes, reliability and easy 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.。

·The main circuit uses the high strength DMC (SMC) unibody half-barrel insulation structure, with good rigidity, high dielectric strength and good foul-resistance。

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

·The conductive bar has good appearance and durability, Ends outlet wire has the option of same or different direction, so it is user-friendly。

Electromagnetic system

·Options of permanent magnetic mechanism or traditional electromagnetic mechanism are available。

·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. 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 uses self-aligning bearings, with flexible support, the load-carrying capability is seizure-free, axial movement is small, thus the movement performance and consistency are improved。

·The movement ends use the secondary guiding mechanism to ensure the axial movement coaxiality of conductive pole in the vacuum tube。The reasonable action mechanism, this improves the performance and reliability of the contactor，in addition, this makes three-phase synchronization and resilience indexes better than the similar products。

·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。

·The mechanical self-containing equipment has a style of its own, with reasonable structure and it is more reliable for use。

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.。?
