The LA9LC321: Rated IP54, so it seals against dust ingress and splashing water — appropriate for enclosure doors on the plant floor where washdown is occasional but not continuous. The keylock destination is the handle, meaning the interlock physically blocks the handle from being turned to the ON position when the door is open — a standard padlocking provision for lockout/tagout compliance.

Frequently asked questions
What is the IP rating and what does it mean for installation?
The LA9LC321 is rated IP54, meaning it is dust-protected and splash-proof. This suits it for mounting on the door of a control panel in a typical industrial environment where occasional water spray occurs, but not for high-pressure washdown zones.
How does the door interlock mechanism work?
The keylock destination is the handle, so the mechanism prevents the Integral starter handle from being turned to the ON position unless the door is closed. This supports lockout/tagout procedures by allowing a padlock to secure the handle in the OFF position.
