FAQs
Yes. OS306U-V supports single-pole and 3-way configurations using wire leads and a standard 120 V supply. It is designed for flush mounting and does not require a neutral, simplifying retrofits in existing boxes. For multi-location control, ensure proper traveler wiring and the required switch leg connections per the specification sheet.
No neutral required means the switch can operate without a dedicated return neutral conductor in the box. This simplifies wiring, reduces material costs, and speeds up installation in many retrofit projects. Performance remains consistent for a wide range of loads (incandescent, halogen, CFL, LED, MLV, ELV) at 120 V, with maintained closure for reliable operation.
OS306U-V supports INC, HAL, CFL, MLV, LED, and ELV loads, up to 600 W. Wire leads provide straightforward connections for typical lighting circuits in single-pole or 3-way setups. When mixing load types, verify compatibility from the datasheet and ensure that each circuit is within the 600 W rating to prevent nuisance tripping.
Absolutely. With a 450 sq ft coverage range and occupancy sensing, OS306U-V is ideal for hallways, classrooms, and office areas. The flush mount and no-neutral design streamline installations in retrofit projects, while the maintained closure ensures immediate re-illumination when space activity resumes, supporting consistent task lighting and occupancy comfort.
The OS306U-V is cULus Listed and NOM certified, confirming compliance with North American electrical safety standards. These certifications reduce regulatory risk for commercial installations and support safer, dependable operation across varied environments such as offices, schools, and retail spaces.
