Square D 9001KA51 Push Button

Schneider Electric Harmony 9001KA51 is a 30 mm panel-mount pushbutton contact block that pairs with Harmony 9001K or 9001SK operators, delivering one normally open and one normally closed contact in a compact, power-reed mechanism. This NO/NC contact block is rated for 3 A at 240 VAC / 115 VDC, and it comes in a black housing to match Harmony assemblies, facilitating easy integration with existing pushbutton hardware. Compatible with Harmony 9001K and 9001SK buttons, the block provides signaling and interlock functionality for start/stop and control circuits in industrial automation, while conforming to IEC, UL, CSA, EN, and NOM standards. With a 30 mm mounting footprint, it supports clean, standardized panel installations and can be added or replaced within the Harmony modular system without extensive rewiring.
