Toshiba HCV-1KAU Vacuum Contactor 720A 3-Phase 1500V

The Toshiba HCV-1KAU Vacuum Contactor is a three-phase switch rated for 720 A at up to 1500 VAC, delivering reliable high-current switching for motor control and power distribution. It supports 50/60 Hz operation with a 208–1500 VAC maximum, and offers 42 kA interrupting current, 85 kA peak withstand, a mechanical life of 2.5 million operations and an electrical life of 500,000 operations, plus a 100–240 VAC/DC control voltage and 3NO-3NC auxiliary contacts for signaling. This panel-mount, non-latched low-voltage vacuum contactor is designed for motor starters, transformer feeders, capacitor switching, and other industrial power control uses, and is commonly deployed in motor control centers, mining equipment, pumps, compressors, conveyors, transformers, and capacitor banks across industries like mining, water/wastewater treatment, steel, cement, oil/gas, pulp and paper, and power generation. System integrators and OEMs rely on the HCV-1KAU for replacements and upgrades of aging contactors and for power system retrofits within three-phase motor and heavy load applications.
