The GS2AH104 is a direct frontal rotary handle from the TeSys GS range, designed to operate the switch-disconnector mechanism on GS-series units rated 630 A to 800 A per IEC. The black handle offers two positions — O (off) and I (on) — and includes a padlocking provision for lockout/tagout during panel service. It mounts directly to the front of the switch, so the handle position gives a clear visual indication of the contact state without needing to open the enclosure door.
The 630 A / 800 A rating on the handle is the switch current it is designed to operate, not a handle current rating — the handle itself carries no load current. It is the mechanical interface for the switch-disconnector's rotary mechanism. The IEC standard cited means the switch it mates with is designed and tested to IEC 60947-3 for isolation and switching. The padlocking provision is a practical safety feature: it accepts a standard padlock hasp to lock the handle in the off position, which is what a maintenance electrician needs for verified isolation before working downstream.
