Toshiba HCV-1JBU Vacuum Contactor 208-1500V 600A 42KA Int. 100-240V Control

The Toshiba HCV-1JBU is a low voltage AC vacuum contactor, non-latched type, designed for motor starters, transformer feeders, and capacitor-switching applications. It has a rated voltage of 208 to 1500 V and operates at a frequency of 50/60 Hz. The rated operational and thermal currents are both 600 A, with a high interrupting current of 42,000 A. It features a coordination with current-limiting fuses of 50 KA. The contactor includes an electronic control drive unit that accepts a wide standard control voltage of 100 to 240 VAC/VDC. Its performance specifications include a switching frequency of 1200/hour, a dielectric strength of 5.5 KV for one minute, and an impulse withstand voltage of 15 KV. Typical operating times are 60 to 80 ms for closing and 50 to 65 ms for opening at 120 VAC. Built with environment-resistant features like a contained switching arc, the design requires reduced maintenance and no external surge protection. The HCV-1JBU conforms to international standards including UL 508, CSA 22.2-14, NEMA, and IEC 60470, and weighs 59.5 lbs (27 kg).
