The 3SU1500-0AA10-0AA0 belongs to Siemens’ SIRIUS ACT series and serves as a modular 3-position plastic holder designed to mount up to three 22 mm operator control elements (such as pushbuttons, emergency stops, selector switches, potentiometers, or illuminated indicators) in a single horizontal row on control panels and enclosures. This holder provides front panel fixing with standard 22.5 mm cutouts, allowing efficient use of panel space while maintaining clear separation and accessibility for operators in industrial environments.
Constructed from durable black plastic, the holder supports both illuminated and non-illuminated devices from the 3SU1 series without requiring additional spacers or adapters. It accommodates 3-contact elements and works seamlessly with SIRIUS ACT accessories like contact blocks, LED modules, and inscription labels. The design follows DIN standards for panel mounting and is rated for typical industrial ambient conditions, making it suitable for machine control stations, HMI panels, and operator interfaces on production lines, assembly stations, and process control systems.
With a compact footprint and snap-together assembly, installation is straightforward—simply snap the control elements into the holder, secure to the panel with standard 22 mm holes, and wire the rear terminals. Siemens specifies a minimum order quantity of 5 pieces, packaged in bags of 5 for bulk panel building projects. The holder carries CE marking and complies with relevant UL/CSA standards for global applications.
