CKG3-160 250 400 630 7.2[12] AC High Voltage Vacuum Contactor-2
CKG3 series vacuum contactors are composed of insulation frame, metal base, transmission shaft and crutch, electromagnetic system, across the control voltage, armature drives the crutch rotation to open the main contact in the vacuum interrupter. Meanwhile, auxiliary switch breaks power of electromagnetic coil, turns to be permanent-magnet maintenance. After power broke by control loop, energy storage power of power module discharges to electromagnetic coil for degaussing, and the main contact broke under the function of opening spring.
