3KD switch disconnectors up to 1600 A

  • Entry
3KD switch disconnectors are designed for stringent requirements. They are used as main control switches, EMERGENCY STOP switches and repair switches in industrial plants, infrastructure and buildings. All 3KD switch disconnectors are climate-proof and meet the requirements of IEC 60947-1, IEC 60947-3 and VDE 0660-107.


3KD switch disconnectors

3KD switch disconnectors are designed to switch the specified rated current on and off under load. At the same time, they provide an isolating function in all low-voltage circuits.

  • Contact position is clearly visible
  • Locking functions help to prevent unauthorized operation

  • Compact design saves space

  • Wide variety of applications thanks to a range of different operating mechanism designs

  • Supplementary functions can be retrofitted

  • Various service positions are possible thanks to optimized heat dissipation

  • Test function to ensure safe commissioning

  • Comprehensive support through provision of CAx data


  • 3-pole, 4-pole, and 6-pole versions in 5 different sizes
  • Supplied as a complete assembly including direct operating mechanism or as a basic unit without a handle
  • Direct operating mechanism with handle on switch
  • Door-coupling rotary operating mechanism for operation of switch disconnector outside the cubicle door
  • The 3KD offers high reliability thanks to the double break technology:

Double break technology

Position of the operating mechanism modules

To allow optimum utilization of the available installation space, units with front operating mechanisms are available with the operating mechanism module in various positions:

On units with lateral operating mechanisms, the operating mechanism module is positioned on the right- or left-hand side of the 3KD switch disconnector.
