What this handle does on the line
The GS1AH210 is a right-side rotary handle from the TeSys GS range, designed for Schneider's GS1 disconnect switches rated 50-63 A. It gives you a physical, lockable means of isolating power at the panel door — the handle mounts on the right side of the enclosure and operates the switch through the door, with IP65 protection keeping washdown liquids out of the mechanism. The black handle and black front plate are the standard finish for this current band.
On a food-and-beverage or washdown line, that rating lets you mount the handle directly on the enclosure door without a separate boot or cover. The O-position padlocking (lockable in O position) meets the lockout/tagout requirement: you can slip a padlock through the handle to keep the switch in the OFF position while someone is inside the panel. No special adapter needed.
