The GS2AH240 is an external rotary handle from the TeSys GS range, designed for right-side mounting on disconnect switches rated 100 A through 400 A per IEC. It gives you a red handle with yellow front plate, two positions (O-I), and IP65 sealing — meaning the handle assembly itself is washdown-rated, not just the switch body. The handle locks in the O position for lockout/tagout compliance.
The 100 to 400 A switch rated current range tells you this handle mates with the full GS2AH switch family up to 400 A IEC — not a specific amp rating, but the handle's mechanical capability across that span. The IP65 rating means the handle and its seal keep out dust and low-pressure water jets, so it's suited for panel surfaces in washdown areas or outdoor enclosures where the handle protrudes. The lockable O position is the safety-relevant feature: padlock the handle in Off, and the switch stays open for maintenance isolation.
Integration note
Mounts on the right side of the GS switch. The handle front plate is yellow, the handle itself red — standard color coding for a disconnect handle. Two positions only: O (off) and I (on). No spring-return or maintained-center position to confuse. The IP65 seal is on the handle assembly, so the panel cutout stays protected. Padlocking in O position uses a standard shackle — no special lock body required.
