Schneider Electric ZBV-G3 LED Module

Schneider Electric ZBVG3 is a 22 mm Harmony XB4/XB5 light block with an integral green LED that mounts behind a Harmony 22 mm push-button head to provide a clear status indicator on control panels, operating at 110–120 VAC with screw clamp terminals. Designed for front-mount illumination of the XB4/XB5 operators, the ZBVG3 is part of Schneider Electric's Harmony 22 mm illuminated block family and uses standard screw-terminal connections for reliable, tool-free field wiring. As documented by Schneider Electric, this specific variant was discontinued on January 9, 2023, and the manufacturer lists the ZBVG1 light block as the recommended replacement for new installations. Within the ZBV/ZBVG LED light modules, there are multiple voltages and colors available—from 12 V and 24 V to 110–120 VAC and 230–240 VAC, in white, green, red, yellow, and blue—with ZBVG3 representing the 110–120 VAC green option.
