The choice is yours. Whatever your preferred method of working, we provide PTI installation terminal blocks with Push-in connection technology as well as UTI installation terminal blocks with screw connection technology for wiring electrical distribution boards.

Furthermore, the portfolio includes terminal blocks with the new Push-X technology. These terminal blocks enable conductor connections with just one hand with practically no force and tool-free. The potential elimination of the ferrule results in a high savings potential.

The installation terminal blocks and standard modular terminal blocks are equipped with many functions. The entire modular terminal block system also uses the same, standardized accessories, offering a high degree of flexibility for your wiring tasks.

The KNX installation terminal blocks are the perfect choice for the convenient and clear wiring of KNX building automation applications. Implement a space-saving neutral and protective conductor distribution in no time at all with the FIX distribution blocks.

  • Fast tool-free connection with Push-in terminal blocks
  • Time-saving and virtually force-free connection with Push-X terminal blocks
  • Space-saving wiring with screw terminal blocks
  • The same accessories for all terminal block types

Terminal blocks with Push-X technology

The terminal blocks with Push-X technology enable easy connection of rigid and flexible conductors with or without ferrules. Even the smallest and most flexible conductors can be clamped quickly and easily with the pretensioned contact chamber. Simply insert the conductor to the end of the chamber. Pressing down the locking mechanism at the end of the chamber releases the contact spring and snaps it shut rapidly. The terminal blocks are available with a nominal cross-section of 2.5, 6, 10, and 16 mm². In addition to various feed-through terminal blocks, multi-conductor terminal blocks, and double-level terminal blocks, the portfolio also includes functional terminal blocks and disconnect terminal blocks.

Ready-to-connect distribution blocks with Push-in connection

PTFIX distribution blocks

Modern installations are increasingly equipped with residual current devices (RCDs) and residual current operated miniature circuit breakers (RCCBs). The challenge is transferring the neutral conductors downstream of the RCD to the building wiring in as little space as possible. Using the compact PTFIX distribution blocks, the neutral conductor outlets as well as the PE outlets and other potentials can be implemented in a space-saving way thanks to transverse mounting.

And PTFIX offers even more: With the various mounting options available, even difficult installation situations do not present a problem. The eleven color variants ensure clear wiring and clear identification of the potentials. The Push-in direct connection technology allows the tool-free wiring of rigid conductors as well as flexible conductors fitted with ferrules. PTFIX saves time, money, and space.

Push-in or screw connection?

If you want a time-saving solution for wiring rigid wires, then the tool-free Push-in connection of the PTI installation terminal blocks is the right choice for you. You can also connect flexible conductors with ferrules by simply inserting them.

To open the terminal block or to establish the contacting for flexible conductors without ferrules, you can actuate the orange push button with almost any screwdriver or a test probe.

UTI 2,5-PE/L/NT terminal block

If you frequently have to retrofit electrical distribution boards where space is at a premium, the installation terminal blocks with screw connection technology will be a firm favorite. That’s because the UTI installation terminal blocks with an overall width of just 5.2 mm allow you to connect two 1.5 mm² conductors in just one terminal point. The only prerequisites for this are that both conductors are of the same type and cross-section, and that the system or building operator accepts this type of double assignment.

Whatever connection technology you use, you will always create reliable and long-term stable connections.

Color-coded assignment of terminal points to the wire colors

KNX installation terminal blocks

The distribution board quickly becomes overcrowded, especially in the case of star-shaped cabling on the KNX bus system. The color-coded, double-level terminal blocks from the PTTBS 1,5/S family are just 3.5 mm wide and enable clear visual assignment of the terminal points to the wire colors.

In the double function shafts on each level, potentials are connected in any combination, sometimes through bridging, by using standardized bridges. This allows the convenient marshalling of main and reserve wires of the KNX bus system in the distribution board in a width of just 7 mm.
