    Material

    Use epoxy resin insulators, conductive parts made of silver-plated electrolytic copper(99.9%).

  • administration.icon02
    Feature

    Simple installation, with a combination of the main earthing switch, without changing the original install structure of earthing switch. It can be achieved freely switch for manually operated and electrically operated. It's safe and reliable, attempts to prevent the conversion function can be relized on control and protection for the motor.
