Product Description

General description

Introducing our highly anticipated 7.2kv High Voltage Three Poles Vacuum Contactor/Switch for Switchgear! This remarkable series contactor is a true marvel of engineering, designed with 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 is applied to the electromagnetic coil, the armature springs into action, driving the crutch to rotate and open the main contact in the vacuum interrupter. Simultaneously, the auxiliary switch cuts off the power to the electromagnetic coil, transforming into a permanent-magnet maintenance mode.
But that's not all! When the power is interrupted by the control circuit, the energy storage power of the power module discharges to the electromagnetic coil, effectively degaussing it. As a result, the main contact breaks under the influence of the opening spring, ensuring a seamless and efficient operation.
Get ready to experience the power and reliability of our 7.2kv High Voltage Three Poles Vacuum Contactor/Switch for Switchgear. With its cutting-edge features and exceptional performance, this contactor is the perfect choice for any high voltage application. Don't miss out on this incredible product!
