Schneider Electric 9001KU3 Protective Boot Blue NSMP

9001KU3 is a blue, 30 mm protective boot for Harmony 9001K and 9001SK pushbuttons, intended for non-illuminated models to shield the button from dust and contaminants in demanding environments. Made of silicone, the boot mounts on the front of the panel as a protective boot and is part of Schneider Electric’s KU series of 30 mm boots, with KU3 designated for the blue color. It is specified for use with non-illuminated 30 mm pushbuttons and carries UL, CSA, and CE approvals, reflecting compliance with common safety standards for control-panel components. The unit is designed for front-of-panel installation and is commonly used in industrial applications where protection from dust, splash-downs, or washdowns helps extend button life and reduce maintenance. In Schneider Electric’s KU family, blues are KU3, with other colors available for different environments, and the 9001KU3 entry is listed in regional catalogs and distributor data as a dust boot for 30 mm non-illuminated pushbuttons.
