This phase-controlled high-voltage vacuum contactor can selectively switch phases in three-phase circuits as required. It is suitable for electrical control equipment with an AC frequency of 50Hz, rated working voltage up to 12kV, and rated working current up to 630A, used for opening and closing the load circuit of electrical control equipment.

This vacuum interrupter switch is a three-phase integral structure, with each phase equipped with an independent operating mechanism, allowing for selective operation on the three-phase circuit as needed. It can operate in either single-phase or synchronized mode.

The design of this switch reduces the space occupied by installing multiple single-phase vacuum switches in the original cabinet, making installation more convenient. Its main operating mechanism uses an independently developed quick direct-acting type, offering advantages such as strong breaking capacity, fast speed, small bounce, and easy maintenance.

CKG4-12XL zero-bounce model, designed to prevent damage caused by bouncing to switching equipment, we have developed a anti-bounce mechanism that absorbs the counterforce at the closing position, resulting in zero bounce for the contactor, greatly reducing the re-ignition arcs, overvoltage, and overcurrent caused by bouncing. After reducing the capacity, it is particularly suitable for equipment with capacitive loads.

The CKG4-12XF enclosed model is designed to meet the diverse application needs of various market fields, featuring anti-contamination, anti-corrosion, anti-burn, and long service life. It is particularly suitable for electrical equipment in the electro-control systems of polycrystalline silicon reduction furnaces.
