Our Top Applications

Installations in Doorbell and Loudspeaker Systems

For extra-low voltage installations such as the installation of doorbell and loudspeaker systems, we recommend the 243 Series.

Advantages of the installation terminals blocks:

  • Maintenance-free installation
  • High wiring density thanks to a compact footprint
  • Conductor range: 0.6 ... 0.8 mm2 (19 ... 18 AWG)

Wiring in Distribution Boxes

Space is always in short supply for installation in a distribution box. Therefore we recommend using the 2273 Series PUSH WIRE® Connector for Junction Boxes.

Advantages of the PUSH WIRE® Connector for Junction Boxes:

  • Compactness: 50 % smaller connector saves valuable space in the box
  • Safety: highly transparent housing to visually verify that the conductor has been properly inserted
  • Conductor range: 0.5 ... 2.5 mm2 (20 ... 14 AWG)

Wiring Fine-Stranded Conductors in Junction Boxes

For wiring fine-stranded conductors in junction boxes, we recommend the 221 Series Installation Terminals Blocks.

Advantages of the installation terminal block:

  • Compactness: for limited space in the junction box
  • Convenience: easy connection due to lower actuation force
  • Safety: convenient testing even after installation thanks to two test slots

New Installation in Small Distribution Boxes

For installation in small distribution boxes, we recommend using the 2003 or 2005 Series Multilevel Installation Terminal Blocks.

Advantages of the multilevel installation terminal blocks:

  • Push-In Termination of Solid Conductors
  • Range of multifunctional jumpers
  • The fastest marking system
  • For the highest current load on the market
