Eaton OS306U-BK Occupancy Sensor Switch - NOM cULus

No neutral required—this occupancy sensor switch eliminates the need for a dedicated neutral conductor during installation, reducing wiring complexity and material costs. This translates into faster, cheaper retrofits and fewer field wiring issues on older fixtures. In practice, it makes it ideal for offices, lobbies, and classrooms where neutrals are absent or hard to access. Equipped for 120 V operation, the OS306U-BK supports both single-pole and three-way configurations, enabling flexible control of lighting across corridors, conference rooms, and multi-branch spaces. The business impact is broader compatibility with existing wiring layouts, reducing the need for panel rewiring and enabling seamless integration into retrofit projects. The 450 sq ft sensing range ensures reliable occupancy detection in typical mid-size rooms and zones, delivering consistent on-off behavior without false triggers. The application benefit is improved energy efficiency and user comfort in spaces such as classrooms, open offices, and break rooms, where occupants enter and exit frequently. Broad load compatibility—supporting ELV, CFL, HAL, FLR, INC, MLV, LED—reduces replacement risk and simplifies procurement. This means you can deploy in mixed-load environments like conference centers with LED fixtures and assorted ballast types, lowering total cost of ownership. Flush mounting and wire leads offer clean installation and secure wiring in standard wall boxes, while the maintained closure (on) behavior ensures immediate illumination in occupied spaces. Certifications NOM cULus Listed provide regulatory confidence on job sites across regions, supporting compliant procurement and installation.
