Product Description

• The Siemens SIRIUS ACT 3SU1 selector switch assembly is designed for industrial machinery, electrical control panels, marine equipment control systems, and automation applications requiring a two-position rotary selector with multiple contact outputs.
• The assembly features a white-and-black long-handle selector operator with a silver metal bezel, designed for compatible 22 mm panel mounting applications.
• Three Siemens 3SU1400-1AA10-1BA0 contact modules are installed on the rear mounting holder. Each module features one normally open (NO) contact with screw terminals, providing three individually accessible normally open contacts within the complete assembly.
• A three-module mounting holder supports the installed contacts and secures the assembly to the selector operator. The mounting arrangement is consistent with Siemens holder part number 3SU1550-0AA10-0AA0.
• An installed grounding screw/stud is also included. This grounding component supports protective grounding of compatible metal operator assemblies when installed and wired according to Siemens requirements. The grounding accessory is consistent with the Siemens SIRIUS ACT grounding screw family, including part number 3SU1950-0KK80-0AA0, although the exact screw variant has not been independently confirmed.
• The selector head is visually consistent with Siemens part number 3SU1052-2CF60-0AA0, a two-position long-handle metal-bezel selector. The precise head MPN and whether the operator is maintained or spring-return have not been independently verified.
