Product Description

General description

Get ready to experience the power of the 12kv High Voltage Five Poles Vacuum Contactor! This bad boy is made up of an electrical insulating frame, metal base, shaft and crank arm, electromagnetic systems, permanent magnet, power modules, auxiliary switches, and vacuum interrupters. When the control voltage hits the electromagnetic coil, the armature kicks into gear and rotates the crutch to open the main contact in the vacuum interrupter. And get this - the auxiliary switch cuts off the power of the electromagnetic coil, turning it into a permanent-magnet maintenance machine. When the power is broken by the control circuit, the energy storage power of the power module discharges to the electromagnetic coil for degaussing, and the main contact breaks under the function of the opening spring. So if you're looking for a top-of-the-line contactor that can handle high voltage and five poles, look no further than the 12kv High Voltage Five Poles Vacuum Contactor!
