CKG4-12 High Voltage Vacuum Contactor
This series of high-voltage vacuum contactors, the AC vacuum contactors are suitable for AC 50-60HZ, the main circuit rated voltage is 7.2 (12) KV, the rated current from 160A to 1600A (160A to 630A) power network system, for long-distance connection and disconnection and the problem of starting and controlling AC motors, transformers and capacitor banks and other occasions.
Third, the same period is good, and the mechanical characteristics are stable.
The closing bounce is small.
The resistance of the main circuit is ≤ 200 (μΩ) and the reliability is high.
Good value for money.
