The housing foot is designed to be "universal" so that the terminal blocks can be snapped onto both relevant mounting rail profiles.
The fine cross section grading up to 240 mm means that the terminal block can be adapted to the current conductor cross sections without taking up much space or costing large sums of money.
The insulation housings of unbreakable polyamide 6.6 have closed cable funnels, in order to simplify the introduction of the conductors.
All modular terminal blocks can be individually and rationally labelled.
