Schneider Electric XB4BW31B5 Harmony XB4 Illuminated White Flush LED 24 V AC/DC 1NO+1NC Push Button

The Schneider Electric XB4BW31B5 is a Harmony XB4 illuminated push button with a chromium-plated metal bezel, a white flush head with a plain lens and an integral universal LED rated for 24 V AC/DC supply. The 1 NO + 1 NC contact block switches through screw-clamp terminals, drawing 18 mA, and the sealed body carries IP66, IP67, IP69 and IP69K protection for a 22.5 mm panel cutout.

Selection Notes

The XB4BW31B5 replaces the replaceable BA9s bulb of the BW3x65 illuminated range with an integral LED, so the 18 mA draw is fixed and there is no lamp to source separately — choose it when the panel feed matches 24 V AC/DC and low-maintenance combined push/indicate duty matters more than reusing existing BA9s stock. The 1 NO + 1 NC contact pair lets the same head drive a start command and a confirmation signal back to the lamp circuit. The flush white profile sits close to the panel face, which reduces accidental actuation compared with a projecting head, and the 100,000 hour LED service life outlasts the BA9s bulb it replaces.

Applications

Used where a single 22 mm cutout needs a momentary white push button with its own low-maintenance LED indication, on panels supplied at 24 V AC/DC.
