The Schneider XB4BW16B5 is a 22 mm illuminated pushbutton from the XB4 metal range, designed for panel-mount control stations. The chromium plated metal bezel gives it a corrosion-resistant finish suited to washdown or outdoor environments — NEMA 4X/13 means it withstands hose-directed water, dust, and oil, so it fits food processing, chemical plants, or marine panels. Rated 10 A in DC-13 and AC-15 utilisation categories, it switches inductive loads like contactor coils and solenoid valves. The 22 mm mounting diameter is the industry-standard hole size for metal pushbuttons.
The 10 A rating at DC-13 is the inductive DC switching limit — that is the number that governs real-world coil or solenoid loads, not the higher AC-15 figure.
