Siemens 3SU10522BF400AA0 2-position Selector Switch Authentic

The SIEMENS 3SU10522BF400AA0 is a 2-position selector switch designed for industrial control panel and machine control applications. This switch provides a reliable, manual-actuated switching action that allows an operator to select between two discrete circuit states. It is a compact, panel-mount component used in control circuits for motor starters, machinery, and process equipment. Electricians and industrial control technicians install this type of switch when a durable, operator-interface device is needed for direct circuit selection in low-voltage control systems.

This selector switch is suited for use in industrial and commercial control panel builds, machine tool wiring, and equipment control stations. Its compact footprint makes it a practical choice for space-constrained enclosure layouts. It ships in a single-unit pack, making it appropriate for individual panel builds or direct replacement of a failed switch in an existing control assembly.

Key Features

• 2-position selector action for discrete on/off or mode-selection control circuits
• Compact dimensions fit standard panel cutouts in industrial enclosures
• Lightweight construction at 0.044 pounds for easy panel integration
• Single-unit pack for straightforward procurement on individual jobs
• OEM Siemens part for consistent fit and performance in Siemens control assemblies

Compatibility

Designed as an OEM-style replacement or new-build component for industrial control panels and machine control stations requiring a 2-position selector switch in the Siemens 3SU1 series operator interface product family.

Installation Notes

Installation is performed by a licensed electrician or qualified control panel technician. De-energize and lock out the control panel circuit before removing or installing any operator interface device, following NFPA 70E lockout/tagout procedures. Verify the panel cutout dimensions match the switch body before mounting. Consult the Siemens 3SU1 series product documentation for wiring terminal torque requirements and contact block configuration.
