HCV-1JBU Outline Drawing

HCV-1KAU Outline Drawing

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.

ABB Contactors

Many Configurations of accessories are possible depending on whether these are front-mounted or side-mounted. AF16(Z) contactors are used for controlling power circuits up to 690 V AC and 440 V DC. They are mainly used for controlling non inductive or slightly inductive loads. These contactors are suitable for controlling 2 separate circuits or 1 circuit comprising 2 separate loads with a single supply. When the contactor

TCI Line Reactors

Trans-Coil CAPGuard KTR tuning reactors are designed to be used in conjunction with power factor correction capacitors whenever nonlinear loads are present. Tuning reactors can be installed with existing power factor correction banks or as part of a new installation. Typical applications include any facility that applies power factor correction capacitors to avoid penalty or to allow for more efficient energy consumption.
