Mounting Variants for Every Application

WAGO’s Miniature Rail-Mount Terminal Blocks offer several mounting options for exceptional flexibility. They can be mounted directly on a 15 x 5.5 mm (0.5 x 0.27 in.) DIN-15 rail or on a mounting plate with a flange or snap-in mounting foot.

Push-in CAGE CLAMP® Actuation Variants

WAGO’s Miniature Rail-Mount Terminal Blocks are available with two actuation types: terminal blocks with push-buttons or operating slots. Either type allows Push-in CAGE CLAMP® terminations.

Advantages of push-buttons:

  • Use any standard operating tool.
  • The orange color highlights the actuator, giving users a clear overview at a glance.
  • The push-button has become synonymous with convenience, making it the industry’s go-to solution for in-the-field wiring.

Advantages of operating slots:

  • The tool remains in the operating slot – both hands are free for wiring.
  • After insertion, the operating tool marks the clamping point and keeps it open.

A Comprehensive Range of Accessories

The WAGO Miniature Rail-Mount Terminal Block is the smallest version in the TOPJOB® S portfolio. Since it’s part of the same portfolio, the industry-trusted TOPJOB® S accessories are also compatible with the miniature rail-mount terminal blocks:

  • Range of jumpers: The standard TOPJOB® S Jumpers can be used. For example, use the pre-assembled jumpers for a star connection (2000-405/011-000) or a delta connection (2000-406/020-000).
  • Marking strips: WAGO’s continuous marking strip enables time- and cost-saving marking – up to three lines at once.
