CKJ5-630 /1140AC vacuum contactor is the next-generation product developed by the company through summarizing many years of users' experience and designed based on the improvement opinions on existing products, therefore, we have remarkably improved the product both in performance indexes, reliability and easy maintenance. It has the advantages of high breaking capacity, oxidation resistance of contact, non-exposing of arc, safety & reliability, long service life, maintenance-free and low noise, etc. Its excellent on-and-off technique assures capability of frequent operations & usages under particularly harsh conditions. It is suitable for conditions including control & protection of motors and electrical control, etc. It is widely used in electrical equipment control in various industrial fields. It can completely replace the traditional electric appliance for use, it has economic efficiency for use.

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.

·Fully insulated framework, with unique, reasonable and compact structure, having elegant appearance and small volume.

·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. 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 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.

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.
