Ckg4-400 400A 10kv 12kv 3 Pole High Voltage Vacuum Contactor
The CKG4-400 high voltage vacuum contactor is a reliable switching device designed for medium-voltage power systems. With a rated voltage of 10kV/12kV and a rated current of 400A, this 3-pole vacuum contactor is widely used for the frequent switching and control of AC motors, transformers, capacitor banks, and other high voltage electrical equipment.
Equipped with a vacuum interrupter, the CKG4-400 ensures safe arc extinction, long electrical life, and low maintenance requirements. Its compact structure, high breaking capacity, and durability make it an excellent alternative to vacuum circuit breakers when combined with fuses and protection devices.
