Introducing our Advanced 7.2kv Single Pole Vacuum Contactor, the perfect solution for high voltage applications! This top-of-the-line contactor is designed with an electrical insulating frame, a sturdy metal base, a reliable shaft and crank arm, and an array of essential components including electromagnetic systems, a powerful permanent magnet, power modules, auxiliary switches, and vacuum interrupters.
When the control voltage is applied to the electromagnetic coil, the armature swiftly drives the crutch into rotation, effectively opening the main contact within the vacuum interrupter. Simultaneously, the auxiliary switch disconnects the power supply to the electromagnetic coil, transforming into a permanent-magnet maintenance mode. This ensures optimal efficiency and longevity.
Once the control circuit breaks the power supply, the energy storage power of the power module is discharged to the electromagnetic coil, effectively degaussing it. As a result, the main contact is safely broken under the influence of the opening spring.
Our Advanced 7.2kv Single Pole Vacuum Contactor is the epitome of reliability and performance. With its cutting-edge design and superior specifications, it guarantees seamless operation in high voltage applications. So, whether you're in need of a contactor for industrial or commercial purposes, our product is the ultimate choice.
