When components are subjected to strong vibrations – in the rail industry, in wind power plants or in mechanical engineering – this requires maximum contact reliability. The spring-cage connection gives you a constant connection: the spring-cage always exerts the same force on the conductor, regardless of the influence of the user.

Your advantages

  • No restriction on cross sections when using conductors with ferrules
  • Low logistics costs thanks to uniform accessories
  • Comprehensive range of accessories: standardized for bridging, testing, and marking

Spring-loaded conductor connection

Reliable contact in a compact design  

Reliable contact in a compact design

The spring-cage connection from Phoenix Contact is extremely user friendly thanks to its front connection:

  1. You can open the terminal point with a standard screwdriver.
  2. Insert the conductor into the clamping space and remove the screwdriver. The conductor makes contact automatically.

A large connection space in an extremely compact design – these are further advantages of the patented spring-cage technology. They allow you to wire conductors with a nominal cross section either with or without ferrules. You can clamp all types of copper cables up to 35 mm² without pretreatment.

Double function shaft

Simple potential distribution with plug-in bridges  

Simple potential distribution with plug-in bridges

Connect up to 50 modular terminal blocks in just one step – with 2- to 50-pos. jumpers.

And that's not all: two potentials can be routed in parallel through a terminal point in the double function shaft. Simply disconnect individual contact tabs from the standard bridge, and bridging between non-adjacent terminal blocks is established. The contact points can also be marked.

Large-surface labeling

Work efficiently with clear labeling  

Work efficiently with clear labeling

The clear marking of the terminal points is essential for reliable and quick installation. In addition to the center marking of the modular terminal blocks, each terminal point can also be labeled separately.
