Overview
The three-tier plug-in terminals offer optimum operating charac-
teristics for modern building installations. The plug-in terminal al-
lows the tool-free wiring of solid conductors.
These terminals can be used interconnected with the neutral
busbar 10 × 3 mm.
Note: Only Cu busbars must be used.
Thanks to their compact design, the three-tier terminals can be
installed in all types of building distribution boards. A load circuit
can be wired quickly and easily, for example, with a 5.2 mm nar-
row installation terminal with terminal size 2.5 mm² and PE/L/NT
terminals.
The double bridge slots support a multitude of individual switch-
ing tasks. This also means it is practical and convenient to make
subsequent modifications to the installation.
