KCFC1-12 series stationary type AC high-voltage vacuum contactor-fuse combined electric appliance is brand new generation of product developed by the company in response to market demand.Through combination with the high voltage fuse having short-circuit current limiting and the cut-off capacity, we have perfected the usage experience of vacuum contactors and improved the adaptability of the product.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.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))

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.

? Contactor and fuse bases adopt unibody frame insulation structure, with good rigidity, high structural stability, high dielectric strength and good foul-resistance。?

?Front face frame uses unibody insulation box structure perfectly insulated from secondary circuit and outside。

? The conducting bar has good appearance and durability, the outlet wire direction is on the same side and it is user-friendly。

Electromagnetic system

? Options of permanent magnetic mechanism or traditional electromagnetic mechanism are available.

? Built-in large capacity sealed auxiliary switch ,this can greatly improve the reliability of the auxiliary switch and it can be used safely。

? It is equipped with fuse auxiliary switch and it can output fusing signals of the fuse。?

? 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。

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,to ensure that 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

? The control circuit terminals adopt rail mounted large capacity terminals, they are equipped with functional flags to prevent wiring errors。
