CKJ5V-1140V AC vacuum contactor is suitable for an AC 50-60 Hz electric power system, with highest operating voltage of 1140V for direct or remote on-off control of the main circuit.
Especially suitable for controlling of frequently operated of the motor, or other loads. It features of reliability, long lifetime, less maintenance, and safety. It has proven the very obvious economic benefit with this kind of product to replace the conventional products.
The vacuum contactor mainly consist of vacuum switch tube (vacuum interrupter), base, rotating arm of force, electro-magnetic coil, opening spring, contact spring, spacing part and so forth. When the electro-magnetic coil gets power, attract the moving armature to drive the rotating arm of force do anticlockwise rotation. The rotating arm of force, by way of contact spring, press the moving contact and fixed contact in the vacuum switch tube to touch, then the main circuit will make. After the power to the electro-magnetic coil cut off, the moving armature, by the effect of opening spring, drives the rotating arm of force to do clockwise rotation.
After the over travel H, the rotating arm of force drives the moving contact rod to press the moving contact and fixed contact separate, then the main circuit will cut off. Because of the spacing component, the rotation angle of the rotating arm of force if fixed and never change.
The vacuum switch tube consists of moving/fixed contact, bellow, conducting rod, ceramic enclosure and so forth.
