Schneider Electric SLSPWS1277UW Wall Switch Occupancy Sensor

Schneider Electric’s Square D SLSPWS1277UW Wall Switch Occupancy Sensor is a single‑circuit PIR device designed to replace a standard wall switch and automatically control lighting on 120 or 277 VAC circuits. The white sensor supports up to 1000 W of tungsten loads at 120 V and up to 1800 VA ballast loads at 277 V (with a 1/4 HP motor limit), making it suitable for commercial spaces such as offices, corridors, and classrooms. It features a 180‑degree field of view with typical coverage rated at 300/1000 sq ft, a built‑in light‑level sensor to prevent activation under daylight, and an LED motion indicator for status visibility plus a manual bypass for local override. The unit includes a line‑selector switch to choose between 120 V and 277 V input and is designed for easy wall‑switch replacement installation. It is UL and cUL Listed and complies with FCC Part 15 and Title 24, rated for operation from 32 to 122 °F (0 to 50 °C) and up to 90% relative humidity non‑condensing. Color is white, catalog number SLSPWS1277UW, and it is part of Schneider Electric’s Square D occupancy sensor family, delivering energy savings without sacrificing convenient control in commercial environments.
