Schneider Electric XVUC21B Tower Light

Schneider Electric XVUC21B is the base unit with top cover for Harmony XVU 60 mm modular tower lights, offered in black and designed for a 60 mm signaling tower. It is built to be paired with the XV6 base module to form a complete 60 mm tower indicator for industrial equipment, mounting on panels, walls, poles, or directly to machinery with a Direct/Tube Mount Adapter. The base unit incorporates a 24V AC/DC power base and includes the top cover, with the XV6 base module and a dark grey XV6C21B body color specification guiding the assembled appearance. This configuration serves as the foundation for a full tower light that conveys machine status from a distance when combined with the compatible indicator modules in the Harmony XVU family. Note that Schneider Electric has listed XVUC21B as discontinued in multiple regions (US: discontinued February 27, 2026; UK: discontinued May 31, 2026), with XV6C21B cited as the recommended replacement to maintain compatibility within the 60 mm modular tower light ecosystem. Ideal for control panels, conveyors, presses, and automation stations, the XVUC21B provides a compact, standardized mounting footprint (60 mm) and a 24 V power interface to deliver clear visual signaling in busy industrial environments.
