Practical Tips for TOPJOB®S Multilevel Installation Terminal Blocks

How does wiring with multilevel installation terminal blocks work in control cabinets? What needs to be taken into account for installation and commissioning?

More Room in Control Cabinets with Multilevel Installation Terminal Blocks

Modern building installations are becoming more and more complex, and to save time and costs, distribution cabinets are being more and more densely packed with installation devices and terminal blocks. To keep things organized, WAGO’s practical marking strips are recommended when TOPJOB® S Multilevel Installation Terminal Blocks are used.
The CAGE CLAMP® connection with WAGO’s push-in connection technology makes wiring easy:
  • Solid and fine-stranded conductors with ferrules can be connected by simply pushing them in – quickly and without tools.
  • All other conductor types can be connected easily and safely by first opening the clamp.
  • After insertion, the operating tool keeps the conductor entry open and marks the clamping point, leaving both hands-free for wiring.

Tip: Save Time during Mounting and Operation

Building installation places high demands on rail-mount terminal block systems. In addition to installation and commissioning, it must also be possible to perform regular testing quickly, safely and easily. When WAGO’s multilevel installation terminal blocks are used, insulation resistance can be measured without disconnecting the conductors, as required by standards.

Fast, Safe Installation Thanks to TOPJOB® S Multilevel Installation Terminal Blocks

WAGO’s TOPJOB® S Multilevel Installation Terminal Blocks guarantee fast, safe building installation because they are designed for space-saving wiring applications in standard distribution cabinets. Extremely compact dimensions, like the short installation length, provide maximum space for conductor termination. Featuring a large cross-section range from 0.25 to 6 mm2 (22–4 AWG), these terminal blocks cover all application areas of modern building installations.
