Compatibility & Replacements
The Square D 9001 KR3UH6 is fully compatible with the Schneider Electric Harmony® 9001 series ecosystem. Its modular construction allows field replacement of contact blocks, light modules, and operator heads without purchasing a complete new assembly. For applications requiring different stem lengths, colors, or operator types, the 9001 series offers variants including 9001KR (standard stem), 9001SKR (plastic base for corrosion resistance), and 9001KX (square bezels for multi-function operation). Verify contact block and light module compatibility when specifying accessories. This unit is a direct equivalent to vintage Square D 9001 pushbuttons and compatible with modern Schneider Electric Harmony 9001 modules.
