switch for railways

Hughes series of air break switches (disconnectors) were especially developed for railway, light rail and tram applications. They are built to remain in operation for more than 30 years without major maintenance. The models range for railways includes 1 pole, 1+1 pole and 2 poles versions. Together with our motor drives it provides a complete solution for automation and remote control of the railway and tram electrical networks.

Hughes Power System disconnectors for railways
  • High quality mechanical parts
  • Low life cycle cost
  • High level of insulation
  • Innovative design
  • Silicone insulators
  • Easy to remote control


Hughes' RABS series of disconnectors is designed and manufactured in Sweden for use in railway and light rail applications. They can be operated both manually and via EOA500 motor drives.

The RABS disconnector purpose is to isolate either a part of the circuit or the whole of the circuit for repair, maintenance, etc.


The rabs disconnector model range:

  • RABS1S-15 1 pole disconnector for 15kV for railways and light rail;
  • RABS1S-25 1 pole disconnector for 25kV for railways and light rail;
  • RABS2S-15 1+1 pole disconnector for 15kV for railways;
  • RABS2S-25 1+1 pole disconnector for 25kV for railways;
  • RABS3S-15 2 pole disconnector for 15kV for railways;
  • RABS3S-25 2 pole disconnector for 25kV for railways;

The rabs disconnector components

  • Arcing horns (1) and pre-arcing horns made of copper or stainless steel;
  • Contact set (2) made out of nickel plated high grade copper;
  • Silicone insulators (3);
  • Switch frame made out of specified silicone content steel for best hot dip galvanizing (4);
