Solid-state contactors

Solid-state contactors

Solid-state contactors are far superior to mechanical contactors in terms of switching speed, service life, and robustness. Solid-state contactors work reliably and with stable switching times in dusty or chemically aggressive atmospheres. They switch resistive and inductive loads silently and without wear. The solid-state contactors in the CONTACTRON series are available for single- and three-phase networks and, depending on the type, also provide a reversing function.

Your advantages with our solid-state contactors

  • Reliable and fast switching, thanks to wear-free electronics
  • Robust – resistant to shocks and vibrations
  • Easy wiring, thanks to integrated locking circuit and load wiring
  • Switching capacity up to 18.5 kW
  • Direct start and reversing of three-phase asynchronous motors

Three-phase solid-state contactors

Fast, robust, and durable switching

Solid-state contactors switch different loads in industrial environments silently and wear-free. Benefit from high switching frequencies and load-free switching in zero crossing mode with a narrow width.

Main features

  • End-to-end product range
  • Wear-free and quick switching
  • Temperature range: -40°C ... +60°C
  • Robust against shocks and vibrations
  • Switching currents up to 30 A
  • Superior system availability
  • High operating voltage range of up to 660 V AC

Your Advantages

  • Reduced overall width saves space in control cabinets
  • Longer service life compared to electromechanical solutions due to wear-free semiconductor technology
  • Optimum heat management with integrated heatsink

Solid-state contactors from the CONTACTRON series are available for single- and three-phase networks

Switching large AC loads

Interference-free switching in the power grid: solid-state contactors from Phoenix Contact only switch in zero crossing mode. This means that no high-frequency interfering pulses are generated.

Additional advantages in the field:

  • Easy control – with versions with 24 V DC or 230 V AC input voltage
  • Integrated locking circuit and load wiring
  • In the event that the module overheats, an optional thermal fuse shuts it down
