Schneider Electric 9001KM7 Indicator Light Module

Schneider Electric Harmony Square D 9001KM7 is a 30 mm indicator light block designed for use with the Harmony 9001K and 9001SK control units. It uses an incandescent lamp with a BA9S base and operates on 220–240 V AC, providing a clear, visible status signal on 30 mm compatible pushbutton stations and control panels. The module is intended for direct mounting within the Harmony 9001K/SK family, matching the standard 30 mm footprint used across the series. Typical applications include signaling and status indication in industrial automation, machine control panels, and power/distribution enclosures where a discrete, wired indicator is needed for 230 V environments. The 9001KM7 variant is listed by Schneider Electric as a light block for Harmony 9001K/SK units, and is part of Square D’s legacy indicator lineup, with variants in the same family offering LED options (e.g., KM7LR, KM7LG, KM7LY) for different colors and signaling needs. In addition to basic electrical compatibility, many regional listings note certifications such as UL 508, CSA C22.2, and CE, supporting use in certified industrial environments.
