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

This vacuum circuit breaker features a three-phase integral structure, with each phase equipped with an independent operating mechanism, enabling selective switching of the three-phase circuit as needed. It can operate either individually per phase or synchronously.

The design of this switch reduces the space required for installing multiple single-phase vacuum switches in the original cabinet and makes installation more convenient. The main operating mechanism uses a self-developed quick direct-acting type, offering advantages such as strong breaking capacity, fast speed, minimal bounce, and easy maintenance.

CKG4-12XL zero-jump model, designed to prevent damage to switchgear caused by jumping, we have developed a anti-jump mechanism that absorbs the reactive force during closing, thus eliminating the contactor's jump and greatly reducing the re-ignition arc, overvoltage, and overcurrent caused by jumping. After reducing capacity, it is particularly suitable for equipment with capacitive loads.

CKG4-12XF enclosed model is designed to meet the diverse application needs in various market fields, featuring anti-contamination, anti-corrosion, anti-burn, and long service life. Particularly suitable for electric control equipment in multi-crystalline silicon reduction furnaces.
