2016 Toshiba HCV-1JBU Lv VAC Contactor, 208-1500 V, 600 a, 42 Ka, IC, 100-240 V

The Toshiba HCV-1JBU is a low-voltage vacuum contactor suitable for motor starters, transformer feeders, and capacitor switching applications. It is rated for a voltage range of 208 to 1500 V and features a rated operational current of 600 A, with a rated thermal current also at 600 A. The contactor offers a high interrupting current of 42,000 A and is designed for protective coordination with current-limiting fuses for prospective short-circuit currents up to 50 KA. It conforms to standards like UL 508 and IEC 60470. The HCV-1JBU includes a solid-state electronic control drive unit that accepts a wide standard control voltage of 100 to 240 VAC/VDC and has a low holding burden of 50 VA. This electronic design minimizes current chopping, which eliminates the need for external surge protection in most applications. The unit has a mechanical life of 2.5 million operations and an electrical life of 500,000 operations, with a maximum switching frequency of 1200 per hour. It features a 3NO-3NC auxiliary contact arrangement and has a weight of 59.5 lbs (27 kg).
