Vacuum isolating phase change switch 3.6KV 800A

The GHZ series three-phase AC high-voltage vacuum isolating phase change switch is purely manually operated. This three-phase AC high-voltage vacuum isolating phase change switch is suitable for 50 Hz power systems with a main circuit rated working voltage of 3.6 kV and a rated working current of 800 A or below. It is used for pre-stage isolation of starters, changing phase sequence, and can disconnect the circuit under certain conditions. It features a small size, simple structure, lightweight operation, small contact gap, short arcing time, and high breaking capacity.
