RITTER single pole switch disconnectors for direct current of the type series RGL for 1000 V DC are switch disconnectors used for railway applications with a breaking and making capacity in both current directions according to EN 50123-3 and IEC 61992-3.

These switch disconnectors for direct current are used in third rail systems and overhead line systems for coupling or disconnecting of the feeding systems.

The switch disconnectors achieve the conditions for disconnectors, for this reason they are suitable for isolating and earthing for personal safety.

The two-step contact system, consisting of main contact and arcing contact in combination with the arcing chamber and an electromagnetic blow-out arrangement, guarantees a high brea- king capacity as well as a safe interruption of low current. The switching performance for low current had been tested according to EN 50123-2, IEC 61992-3 with a voltage of 1000 V DC.

Switch Disconnectors for Direct Current Features:

  • compact construction
  • high breaking capacity
  • short circuit making capacity
  • reliable breaking of low current
  • long lifetime due to the use of corrosion-resistant materials
  • small maintenance effort due to their simple and robust construction.

The switches are suitable for all kinds of indoor application. They are used in substations or beside the track in outdoor cubicles.
