D11 Main Switches


D11 main switches conform to IEC60974-3. They meet the requirements of disconnectors, main switch and maintenance switch which is suitable for ventilation, air-conditioning, water pump system, industrial unitized device, safety isolation and other distribution switches.


  • Reliability
    The breaking contact of switch has long insulation, reaching 13-14mm that far more than safety requirement of VDE0113. In most cases, our
    switch’s safety rating surpass most existing switches.
  • Flexible Mounting
    The switches are both suitable for panel mounting and base mounting. Base mounting can be installed convenientiy and safely with screw and
    35mm Din Rail. This switch system owns the largest flexibility and adaptability. We need not remove switch when adding attached contactor
    and neutral terminal.
  • Convenient Mounting
    Built-in screw can avoid the trackslip in doing manual operation, enabling air operated and power-driven tool to give full play to their
    performance, ensuring the safety and speed of mounting.
