Overview
Terminal size 2.5 mm²
Four-tier motor terminals with terminal size 2.5 mm² are particu-
larly suited for the compact wiring of three-phase loads. They
have three through-type tiers and a PE terminal which makes
contact when it is simply snapped onto the support rail.
Each clamping point has a facility for inscription and a test op-
tion for 2.3 mm test plugs.
There is also sufficient space to make a large marking in the cen-
ter of the terminal.
No cross-linking option.
Terminal size 4 mm²
Like the 2.5 mm² version, the four-tier motor terminal with 4 mm²
also enables three phases and the PE to be wired in one termi-
nal. This terminal is enclosed on both sides.
No cross-linking option.
Integrated PE/ground conductor function
PE contact with the support rail is made by simply snapping the
terminal onto the rail. The four-tier motor terminal with terminal
size 4 mm² is therefore particularly suited for the space-saving
wiring of three-phase loads.
