  • Easy ring cable lug connection thanks to the screw connection principle with spring-loaded screw; maintenance-free with integrated screw locking
  • Easy and tool-free direct plug-in thanks to push-in multi-conductor connection
  • Simple potential distribution with time-saving jumper system
  • Safety for users thanks to integrated shock protection
  • Maximum overview thanks to extensive marking and labeling of every terminal point
  • Reduction in logistics costs with the uniform CLIPLINE complete system accessories

Screw connection principle with spring-loaded 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 to use – high-performance connection:

  • Direct tool-free conductor connection for either solid conductors or pre-assembled conductors with ferrules
  • The special spring profile enables easy insertion of conductors with ferrules of 0.25 mm² or greater, while simultaneously maximizing conductor pull-out forces
  • The actuation lever permits easy conductor release using any type of tool, without direct contact with live parts
  • For connecting stranded conductors from 0.14 mm² without ferrules, the lever must simply be actuated during insertion

Push-in terminal blocks

Terminal blocks with push-in connection  

Push-in terminal blocks

The PT range of terminal blocks with push-in connection technology gives you the right terminal block for every task, from 1.5 mm² to 150 mm².
Various terminal block ranges ensure every application's requirements are addressed, such as the railway industry, energy technology or explosion-protected areas in the process industry.

The terminal blocks make use of the advantages of the CLIPLINE complete system. All connection technologies can be freely combined with the standardized system accessories.
