Toshiba HCV-5HA Vacuum Contactor

Description:

The Toshiba HCV-5HA Vacuum Contactor is used to switch and control medium-voltage motors, transformers, and power distribution circuits in industrial electrical systems. Commonly installed in motor control centers (MCCs), mining equipment, power generation facilities, water and wastewater treatment plants, cement plants, and heavy industrial machinery requiring a 7.2 kV, 400 A vacuum contactor. Maintenance technicians, OEMs, and system integrators use this vacuum contactor for replacement of worn contactors, switchgear repairs, motor control retrofits, and restoration of reliable medium-voltage switching performance.

Applications:

The Toshiba HCV-5HA Vacuum Contactor provides high-performance switching for medium-voltage induction motors, transformers, capacitor banks, and industrial distribution circuits. It is widely used in mining operations, steel mills, chemical processing plants, oil and gas facilities, power generation stations, water and wastewater treatment plants, and industrial automation systems where long service life and low-maintenance vacuum interruption are required.
