Square D 9001KN8330 Round Legend Plate Emergency Stop

Product Description

The SQUARE D 9001KN8330 is a round plastic legend plate marked Emergency Stop, designed for use with industrial control stations and operator interface assemblies. It features a yellow background with black lettering, providing high-contrast visibility required for emergency stop identification in compliance with common safety standards. The plate has a 30mm hole diameter and a 90mm overall diameter, fitting standard 30mm cutout mounting arrangements. Licensed electricians and industrial maintenance technicians typically install this component during panel assembly or operator station servicing.

This legend plate is suited for use in industrial, commercial, and manufacturing environments where clearly labeled emergency stop controls are required. It is a direct-fit component for selector switch assemblies and push button stations that use the standard 30mm form factor. The plate installs without tools in most configurations, snapping or sliding into the legend plate carrier on the operator device.
