Square D 9001KN209 Half Round Aluminum Legend Plate

Product Description

The SQUARE D 9001KN209 is a half-round aluminum legend plate marked with the word OPEN in white letters on a black background. Legend plates serve as identification markers on industrial control panels and operator interface stations, giving technicians and operators a clear visual reference for switch function. This plate features a 1.18 inch hole diameter, sized for standard 22 mm selector switch assemblies. The aluminum construction provides durability in light industrial environments. Electricians and panel builders install this plate as part of a complete pushbutton or selector switch assembly.

This legend plate is intended for use on operator interface panels, control cabinets, and machine control stations where 22 mm selector switches are installed. The OPEN designation makes it suitable for valve control stations, motor starters, and circuit isolation assemblies where the open-state position must be clearly labeled. The black background with white lettering provides strong visual contrast for quick identification in industrial settings.

Installation Notes

Installation is performed by licensed electricians or panel builders during control panel assembly or switch replacement. De-energize the control panel and follow applicable NFPA 70E lockout/tagout procedures before working inside any enclosure. The legend plate snaps or slides into the legend plate holder on the selector switch body. No special tools are required for fitment, but verify hole diameter and plate shape match the switch operator before final assembly.
