Schneider Electric 9001KU6 Protective Boot NSMP

9001KU6 is a yellow, 30 mm silicone rubber dust boot for Schneider Electric Harmony pushbuttons, specifically designed for non-illuminated 9001K and 9001SK heads. It fits the 30 mm footprint of non-illuminated Harmony pushbuttons and shields the internal contact block from dust, dirt, and moisture while preserving normal actuator access. This boot is a standard Harmony 9001K/9001SK accessory (Schneider part number 9001KU6) and carries UL, CSA, and CE approvals in many regions. Schneider Electric notes that KU-series protective boots are recommended for very dirty environments or severe hose-down applications, though they are not required to meet UL Type 4 ratings for Type K or UL Type 4/4X ratings for Type SK; the boot is manufactured from silicone rubber to endure harsh environments.
