nVent ERICO Ericontact Double Rail Contact

DSK22 (715092)

The nVent ERICO Ericontact series of rail contacts provides a superior quality connection to the rail web with a very low contact resistance. The contacts are quickly and easily fitted by means of an insertion tool, regardless of weather conditions. All nVent ERICO Ericontact components are manufactured according to high standards and norms. Tested to the most demanding requirements of the Rail Industry Standards, nVent ERICO Ericontact is the ideal solution for mechanically applied connections such as signal engineering, earthing (grounding), or traction return current. The nVent ERICO Ericontact Double Rail Contact series offers connections on both sides of the rail web. This is a significant advantage when making interconnections in the station area, for example. The nVent ERICO Ericontact Double Contact is ideal solution in confined spaces. With a clearance of only 50 mm between the rail heads, the nVent ERICO Ericontact can still be inserted and the cable lug connected from both sides.


  • Easy to install
  • Very low contact resistance (< 5 μΩ)
  • Same electrical resistance on the two sides of the contact
  • The contact surface of the two copper bushes is made inside the rail
