Schneider Electric ZB4BVBG3 Pushbutton Contact Block

ZB4BVBG3 is a green LED light block for Schneider Electric Harmony XB4 22 mm pushbutton assemblies, designed to provide clear, on‑panel status indication in industrial control panels. This lighting module operates from 24 to 120 V, AC or DC, and uses screw‑terminal connections for straightforward wiring in busy panel environments. The green LED illuminates when the associated pushbutton circuit is energized, delivering immediate visual feedback of status in applications where compact 22 mm signaling devices are used, such as control panels and automation cabinets. Compatible with the Harmony XB4 family, ZB4BVBG3 serves as a dedicated lighting block that can accompany standard XB4 pushbutton bases to complete a signaling solution without replacing the underlying switch body.
