Overview
Plugs can be connected at both sides of the terminal using the
through-type terminals of the combination plug-in terminals. This
makes the combination plug-in terminal system even more flexi-
ble and allows the terminals to be used as connecting elements
between modules.
Plugs with a terminal size of 2.5 mm² enable the use of common
accessories, such as latches, strain relief and shield connectors.
PE terminals with the same contour are available for the base ter-
minals. These are simply snapped onto the support rail to estab-
lish a connection to ground potential.
