3SU14 modules

The contact modules are equipped with a slow-action contact (1 NO contact or 1 NC
contact). These ensure a high contact stability even with small voltages and currents
(e.g., 5 V/1 mA).

Design of a 3SU10 and 3SU11 command point

A modular command point consists of the following elements:
● An actuating or signaling element in front of the front plate
● A holder for securing behind the front plate
● Up to three contact modules in a row (four in the case of 4-slot holders) and / or two
contact modules and one LED module (3-slot holders only) behind the front plate
● A maximum of 3x 2 (1-pole) contact modules can be stacked with a 3-slot holder
● A maximum of 4x 2 (1-pole) contact modules can be stacked with a 4-slot holder
● A comprehensive range of accessories for labeling
Mounting and stacking of the modules on a 3-slot holder
With SIRIUS ACT, the modules are mounted on the holder without any further accessories.
The modules can be stacked without needing to use a tool (max. 2x 1-pole modules behind
one other).
