The GS2AHT540 is an external frontal rotary handle from the TeSys GS range, designed to operate disconnect switches in control panels. It mounts to the enclosure door and gives the operator a mechanical interface to the switch mechanism inside. The handle offers three positions — Test, O (off), and I (on) — and can be padlocked in the O position for lockout/tagout compliance during maintenance. Rated IP65, the handle assembly withstands hose-directed water and dust ingress, making it suitable for washdown environments in food processing, chemical plants, or outdoor enclosures where the door seal is maintained.
The part is designed to IEC standards, which covers the majority of industrial control panels outside North America. For UL 508A panels, verify the specific disconnect switch model the handle mates with, as the handle itself carries no separate UL listing.
