Proven connection technology

Clamping body based on the Reakdyn principle and with multi-conductor clamping  

Screw connection: safe and maintenance-free wiring

Standard terminal blocks are characterized by practical properties. 

  • Maintenance-free conductor connection with the Reakdyn principle – there is no need to tighten the terminal block screws.
  • Clamp all types of copper wire without pretreatment. With a nominal cross section, you can also use splicing protection in the form of ferrules.
  • Multi-conductor connection – two conductors with the same cross section make contact safely in the clamping parts.
  • High contact forces and large contact surfaces – conductor cross sections of up to 240 mm² can be wired gas-tight and with long-term stability.

Flexible plug-in bridge system

Terminal block with one plug-in bridge  

Simple potential distribution with plug-in bridges

Implement potential distribution quickly with the standardized plug-in bridges from Phoenix Contact.

Two bridge shafts in all terminal blocks make flexible chain and level bridging and bridging between non-adjacent terminal blocks possible.

With the 2- to 50-pos. plug-in bridges, you can connect any number of terminal blocks.

Snap-on protective conductor foot

Snap-on protective conductor foot  

Snap on easily and make contact efficiently
