Main contactors

Main contactors are mechanical contactors with a high switching capacity that are used for controlling motors. Solid state contactors, however, work with faster switching times and avoid possible wear because they operate electronically and not mechanically. Solid-state reversing contactors are suited to reverse the direction of three-phase current motors. All types of main contactors are available with AC and DC control voltage. The three-phase contactors are equipped with auxiliary contacts to return the signals to the controller.

Applications of main contactors in industry

Main contactors are typically used in automation and control technology. Examples are:

  • Control of motors and installations
  • Switching on electrical heating systems
