Schneider Electric XB4BVB4 Harmony XB4 Pilot Light Metal Red 22 mm Integral LED 24 V AC/DC Pilot Light

The Schneider Electric XB4BVB4 is a Harmony XB4 pilot light with a chromium-plated metal bezel, a red plain lens and an integral universal LED rated for 24 V AC/DC supply. It mounts into a standard 22.5 mm panel cutout through screw-clamp terminals, draws 18 mA and is rated for a 100,000 hour service life at rated voltage and 25 degC.

Selection Notes

The XB4BVB4 replaces the BA9s bulb of the XB4BV6x range with an integral LED, so there is no lamp to stock or swap and the 18 mA draw is fixed by the light block rather than by whatever bulb gets fitted — pick this variant when the panel's power feed matches 24 V AC/DC and low-maintenance indication matters more than using existing BA9s spares. The red lens gives steady, non-flashing indication, and the 100,000 hour rated service life at 25 degC means the LED will typically outlast the panel it is mounted in. The metal bezel and IP66/IP67/IP69/IP69K sealing match the other Harmony XB4 devices on the same panel.

Applications

Used as a red status or power-on indicator on control panels and operator stations supplied at 24 V AC/DC, wherever low-maintenance LED indication is preferred over a replaceable BA9s bulb.
