Description
The XB5AA31 is a complete, ready-to-install pushbutton from Schneider Electric’s Harmony XB5 range of 22mm modular plastic control and signaling units, designed for Start/Stop control and general machine command functions. It features a green, flush-mount, unmarked operator head with spring return (momentary) action and a single normally open (NO) contact, making it a common choice for start or run buttons on control panels and machine interfaces.
Built with a plastic bezel and fixing collar and silver alloy (Ag/Ni) contacts, the XB5AA31 connects via screw-clamp terminals for straightforward wiring and maintenance. It’s rated for high mechanical durability (10 million cycles) and electrical durability (1 million cycles under typical AC/DC loads), and its IP66/IP67/IP69K and NEMA 4X/13 protection ratings make it resistant to dust, water jets, and washdown conditions — even withstanding high-pressure washer exposure. With a wide operating temperature range (−40°C to 70°C) and multiple marine certifications (RINA, DNV, BV, Lloyd’s Register, GL), the XB5AA31 is well suited for control panels in industrial, marine, and offshore automation environments where reliability in harsh conditions is essential.
