The SCHNEIDER ELECTRIC 9001K97 is a padlock attachment accessory designed for 30mm round pushbutton switches. It mounts to compatible pushbutton operators to allow a padlock to be inserted, physically preventing the button from being pressed during maintenance or lockout/tagout procedures. This part is a switch accessory, not a standalone operator — it adds lockout capability to an existing pushbutton assembly. Electricians and industrial maintenance technicians install this component as part of LOTO compliance setups on control panels, machinery, and equipment enclosures.
This padlock attachment is intended for use with nonilluminated, round pushbutton operators in industrial and commercial control panel applications. It is suited for environments where lockout/tagout requirements under OSHA 29 CFR 1910.147 must be met at the operator level. The small footprint and straightforward installation make it a direct fit for new builds and retrofit applications alike where operator-level lockout is needed.
Designed for use with Harmony 9001K, 9001SK, and 9001KX series 30mm nonilluminated round pushbutton operators as stated by the manufacturer.
Installation is performed by qualified electricians or industrial maintenance personnel. Before attaching or removing any pushbutton accessory, de-energize the control circuit and follow all applicable lockout/tagout procedures per OSHA 29 CFR 1910.147 and NFPA 70E. Verify the attachment is fully seated and that the padlock shackle clears the operator body before returning the panel to service. Do not force the attachment onto incompatible operator styles or sizes.
