CKG3-7.2kV 160A 250A 400A 630A AC High Voltage 3 Phase Vacuum Contactor Price

The CKG3/4-7.2 series AC three-pole high voltage vacuum contactors are designed for 50Hz–60Hz power networks, with a rated voltage of 6.6kV or 7.2kV and a rated current up to 630A in the main circuit. These contactors are widely used for remote switching, frequent starting, and reliable control of AC motors in medium voltage systems.

For enhanced protection and safe operation, the CKG3/4 vacuum contactors are often used in combination with fuses and protective relays, serving as a cost-effective alternative to vacuum circuit breakers. Their compact design, stable performance, and long service life make them an ideal solution for motor control, transformer switching, and capacitor bank applications in modern power distribution networks.
