Description
About the XB4
About the XB4
The Schneider Electric XB4BP51 is a Harmony XB4 modular push button with a chromium-plated metal bezel, a yellow projecting head under a clear boot, and spring return operation. The 1NO contact block switches at 10 A Ith through screw-clamp terminals, and the sealed XB4BP51 body carries IP66, IP67, IP69 and IP69K protection for a standard 22.5 mm panel cutout.

Selection Notes
The XB4BP51 pairs a yellow projecting head with a spring return mechanism, so the button pops back out as soon as it is released and does not hold a latched state — pick it for momentary start/stop commands rather than mode selection. The 1NO contact block determines which circuit function it can drive: the 1NO version closes the circuit on actuation, making it the default choice for a start or reset command. The clear boot over the body keeps the IP66/IP67/IP69/IP69K rating intact in wash-down areas, and the 0.082 kg metal body with Zamak fixing collar outlasts plastic XB5 equivalents under repeated high-pressure cleaning cycles.
Applications
Used as a manual control input on machine control panels and operator stations wherever a yellow 22 mm momentary push button with a 1NO contact is specified, including food, beverage and wash-down environments where the IP69K rating applies.
