Toshiba HCV-6KALU Vacuum Contactor

720 Amp, 2300-7200 Volts (Medium Voltage) This 720-ampere contactor replaces Toshiba's CV461M-KAT(L) and utilizes the latest vacuum and solid state technology developed by Toshiba. The HCV-6KA uses 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. The contactor is available in either electrically maintained or latched type version. The HCV-6KA 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 comparable design of interrupters.
