Toshiba HCV-1JBU/1KAU Vacuum Contactor
Toshiba Updated: 2007-07-18600 Amp, 208-1500 Volt / 720 Amp, 208-1500 Volt (Low Voltage) The HCV-1JBU is Toshiba's 3rd Generation of 600A, low voltage vacuum contactor. With the HCV-1KAU, Toshiba offers the first true 720A, low voltage vacuum contactor (it does not use parallel vacuum interrupters per phase). The HCV-1KAU incorporates Toshiba's patented "Axial Magnetic Field Type Electrode" in the vacuum interrupters. This special design results in higher current interruption and smaller size than any other design of interrupters. The HCV-1JBU and HCV-1KAU contactors use a solid state, electronic control (drive unit), to operate the contactor. The drive unit uses an electronic circuit, and any control voltage between 100V and 240V either AC or DC can be used without changing the coil and/or other parts.
