Eaton OSP10-BK Occupancy Sensor Switch - cULus NOM
Part Number: OSP10-BK
Quick Summary
The Eaton OSP10-BK occupancy sensor switch automatically controls lighting to save energy in commercial spaces. In retrofit projects, wiring neutrals is a common hurdle that can stall installation. It is cULus Listed and NOM certified, meeting key safety standards for North America and select Latin American markets. With no neutral connection and broad 120/277 V compatibility, this sensor simplifies wiring, reduces material costs, and speeds up commissioning. For facilities aiming to improve energy efficiency without compromising reliability, this model pairs with standard wall boxes and existing lighting loads while delivering predictable occupancy-based control.

Feature: No neutral connection. Business impact: Simplifies wiring, reduces labor and material costs. Application: Retrofit and new installations where neutrals are not readily accessible, enabling faster commissioning and fewer box-fill concerns. Feature: Voltage rating of 120/277 V and single-phase operation with load-type compatibility (MLV, ELV, HAL, FLR, INC). Business impact: Broad compatibility reduces the need for multiple sensor variants across circuits, improving procurement efficiency and system reliability. Application: Offices, classrooms, corridors, and other spaces with mixed lighting loads. Feature: Wiring method wire leads, mounting method flush, and maintained closure. Business impact: Quick, clean installation with predictable operation and a low-profile wall presence. Application: Wall-box retrofits and new builds where aesthetic and reliability matter. Feature: Load range and coverage (800 W @120 V INC/HAL; 1200 W @120 V FLR; 2200 W @277 V FLR) and range up to 1000 sq ft; color Black. Business impact: Handles common luminaire loads while supporting medium-sized spaces, enabling scalable lighting control. Application: Conference rooms, lobbies, and open-plan areas. Feature: Certifications and general robustness (cULus Listed, NOM). Business impact: Strengthens code compliance, reduces risk during inspections, and supports installer confidence. Application: North American and select Latin American markets with strict safety expectations.

FAQs
To install, power down the circuit, remove the existing switch, and connect the OSP10-BK using its wire leads per the Eaton diagram for line and load. Ground where applicable, mount flush, and re-energize to test. This model supports 120/277 V single-phase circuits and works in both 1-pole and 3-way configurations, with no neutral required.
The OSP10-BK is rated for MLV, ELV, HAL, FLR, and INC loads. At 120 V, it handles 800 W (INC/HAL) and 1200 W (FLR); at 277 V, it handles up to 2200 W (FLR). These ratings support a wide range of lighting technologies, including LEDs and fluorescent fixtures, in standard commercial spaces.
Yes, the OSP10-BK supports three-way wiring in addition to single-pole configurations. When planning a three-way setup, ensure the companion switch wiring matches the Eaton instructions and the circuit is configured for occupancy-based control. The device uses wire leads for straightforward connections and a flush-mount profile.
The OSP10-BK is cULus Listed and NOM certified, indicating compliance with North American safety standards and select Latin American requirements. These certifications help meet code mandates, reassure end-users during audits, and reduce project risk when deploying in occupied facilities with strict safety guidelines.
The OSP10-BK delivers energy savings through occupancy-based control, simplifies retrofit wiring with no neutral requirement, and reduces material costs and installation time. Its compatibility with common lighting loads and 120/277 V circuits helps standardize procurement, speeding commissioning and delivering measurable ROI through lower energy use and easier maintenance.
