What is a vacuum contactor?

A vacuum contactor is an electrical switching device that uses a vacuum interrupter to open and close circuits under load, commonly applied in medium-voltage power systems.

How does Vacuum Contactor Series interrupt current?

Vacuum Contactor Series interrupts current by separating contacts inside a vacuum chamber, where the absence of gas enables rapid arc extinction during breaking operations.

Which voltage levels are supported by Vacuum Contactor Series?

Vacuum Contactor Series supports rated voltages of 7.2 kV and 12 kV, suitable for medium-voltage distribution and control systems.

How is electrical life defined for Vacuum Contactor Series?

Electrical life for Vacuum Contactor Series is specified by operation counts under AC-3 and AC-4 duty categories, reflecting different load and switching conditions.

Where is Vacuum Contactor Series typically installed?

Vacuum Contactor Series is typically installed in medium-voltage switchgear, motor control centers, and substations where controlled switching and frequent operation are required
