Screw connection principle with spring-guided screw

Convenient ring cable lug connection  

Convenient ring cable lug connection

Convenient and safe ring cable lug connection:

  • Convenient conductor connection thanks to captive and spring-loaded connection screws
  • Automatic screw centering thanks to optimum guidance in the terminal housing
  • Vibration-proof and maintenance-free screw connection thanks to integrated spring washer
  • Simple multi-conductor connection
  • Considerable conductor pull-out forces due to a high contact force and large contact surfaces

Push-in connection technology

Push-in connection technology  

Push-in Technology

Easy application – high-performance connection:

  • Direct, tool-free conductor connection for solid conductors or conductors pre-assembled with ferrules
  • The special spring profile enables easy insertion of conductors with ferrules of 0.25 mm² or greater combined with maximum conductor pull-out force
  • The push button permits easy conductor release using any type of tool, without direct contact with live parts
  • For connecting stranded conductors of 0.14 mm² or greater without ferrules, the button must simply be actuated during insertion

Top quality

Reliable connections – that's our aim. The quality of our products is the key. This starts with the selection of materials.

Metal parts made of copper alloys that are resistant to strain cracking and corrosion:

  • No electrolytic corrosion due to humidity
  • Safe electrical contacts
  • Minimal heating, thanks to good electrical conductivity

Insulating housing made of elastic polycarbonate with high impact strength:

  • Recyclable, halogen-free and UV resistant
  • Good tropical and termite resistance
  • Operating temperatures from -40°C to +130°C
  • Dimensional stability and good heat distortion resistance
  • High chemical resistance
  • Excellent aging characteristics
  • Certification according to UL 94 for flammability rating V0
