Terminal blocks with screw connection from Phoenix Contact meet the demands of most applications. Save time when building rail assemblies with ground blocks that snap on to the rail using a special PE foot and robust plug-in bridges among other operator benefits.

Operator advantages

  • Save time and space with a multi-conductor connections
  • Low maintenance: patented Reakdyn connection principle prevents screw back-out
  • Save money with bridging, marking and test accessories
  • High conductivity with broad range of conductor cross sections up to 500 kcmil (240 mm²)
  • Widely recognized throughout the world

Proven connection technology

Clamping body indicating the Reakdyn principle and multi-conductor connection  

Screw connection: safe and maintenance-free wiring

Standard terminal blocks features.

  • Maintenance-free conductor connection with the Reakdyn principle – terminal block screws are resistant to loosening during high vibration
  • Clamp all types of copper cables without pretreatment - also supports ferruled conductors
  • Support multi-conductor connection – two conductors with the same cross section can be safely terminated
  • High contact forces and large contact surfaces – conductor cross sections of up to 500 kcmil (240 mm²) can be wired and maintain a gas-tight connection with long-term reliability


Flexible push-in bridging system

Terminal blocks with plug-in bridges  

Simple potential distribution with push-in bridges

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

Two bridge channels in all terminal blocks allow for flexible bridging and make "skip" bridging between non-adjacent terminal blocks possible.

With 2- to 50-position push-in bridges available, you can easily connect any number of terminal blocks.

Snap-on ground terminal block

Snap-on protective conductor foot  

Ground terminal block easily snaps onto the rail for a dependable connection

Ground terminal blocks of the same profile can be snapped on easily and make contact with the rail. This efficient mechanical and electrical contaction meets all the requirements of the IEC 60947-7-2 standard.
