Square D GS2AE TeSys GS Shaft Extension for GS2 Fuse Switch-Disconnectors
The Square D GS2AE TeSys GS Shaft Extension is a control accessory that connects an external operating handle to 3-pole and 4-pole IEC/UL fuse switch-disconnectors across the TeSys GS2 range. The extension carries a 320mm shaft length with a 10x10mm cross section, giving installers the flexibility to mount the operating handle at a practical distance from the switch body. This accessory is compatible with GS2E, GS2F, GS2G, GS2J, GS2K, GS2L, GS2M, GS2N, and GS2Q fuse switch-disconnectors, and the TeSys GS2 platform it supports spans motor full-load-amp ratings from 60A up to 400A, covering line ratings from 30A to 400A across the family — including 50A, 60A, 63A, 100A, 125A, 160A, 200A, 250A, 315A, and 400A lines. Whether the application calls for a compact 60A disconnect or a heavy-duty 400A switch, this shaft extension provides the mechanical link needed for reliable external handle operation.
Key Features

- Pole Configuration: Works with both 3-pole and 4-pole IEC/UL fuse switch-disconnectors.
- Amperage Coverage: Supports GS2 switches spanning 60A to 400A motor FLA ratings, with line ratings from 30A to 400A across 50A, 60A, 63A, 100A, 125A, 160A, 200A, 250A, 315A, and 400A lines.
- Control Accessory Category: Purpose-built as a shaft extension for external operating handles, not a standalone switch component.
- Robust and Compact Handles: Supports the TeSys GS2 line's robust and compact external handle design.
- High Short-Circuit Performance: Part of a TeSys GS2 system rated for short-circuit performance up to 100kA.
- Effective Protection: Complements the TeSys GS2 line's fuse speed-fusion protection approach.

Square D GS2AE8 – Frequently Asked Questions
1) Which TeSys GS2 fuse switch-disconnectors does the Square D GS2AE shaft extension fit?
The GS2AE shaft extension fits the GS2E, GS2F, GS2G, GS2J, GS2K, GS2L, GS2M, GS2N and GS2Q fuse switch-disconnectors, in both 3-pole and 4-pole IEC/UL versions. If your switch is outside the GS2 range, this is not the linkage for it.
2) How long is the GS2AE shaft and what is the cross section?
320mm of shaft with a 10x10mm square cross section. That square profile is what keys the shaft into the external handle and the switch mechanism, so the handle has to be built for a 10x10mm shaft. The 320mm length sets how far the handle can sit from the switch body, and you trim to the depth your enclosure needs.
3) Is the GS2AE a switch, or just the linkage between the handle and the disconnect?
It is only the mechanical link. The GS2AE is a control accessory that couples an external operating handle to the fuse switch-disconnector shaft, not a standalone switching component. You still need the GS2 fuse switch-disconnector itself and a compatible TeSys GS external operating handle to make a complete through-the-door assembly.
4) Does the GS2AE cover a 400A disconnect as well as a small 60A one?
Yes. The extension is offered against the full TeSys GS2 band, 60A to 400A motor FLA, with line ratings from 30A up to 400A across the 50A, 60A, 63A, 100A, 125A, 160A, 200A, 250A, 315A and 400A frames. Order by the motor FLA of the switch it is going on: GS2AE8 for 60A and GS2AE2 for 400A.
5) Can an Eaton rotary disconnect shaft extension be used in place of the Square D GS2AE on a GS2 fuse switch-disconnector?
No. The GS2AE is built as a shaft extension for the TeSys GS2 range and is matched to the GS2E, GS2F, GS2G, GS2J, GS2K, GS2L, GS2M, GS2N, and GS2Q fuse switch-disconnectors, with a 320mm shaft in a 10x10mm cross section. The Eaton rotary disconnect shaft extension is made for Eaton SH0/SH00 external handles in the R5/R9 series, so it keys to a different switch and handle system. Shaft extensions are mechanically specific to the switch body and handle they link, so stay within the family the switch belongs to.
6) What do I have to specify when ordering a GS2AE shaft extension?
Specify the motor FLA of the switch you are fitting. Two part numbers are sold: GS2AE8 for the 60A end of the range and GS2AE2 for 400A. Pole count is not an ordering variable, the extension suits both 3-pole and 4-pole GS2 switches.
7) Why would I use an external handle and shaft extension rather than operating the disconnect directly?
A through-the-door handle lets the operator switch and lock out the disconnector with the enclosure closed, which is the normal arrangement for panelboard, enclosure and OEM equipment builds. The GS2AE's 320mm shaft is what bridges the gap between a switch mounted deep on the backpan and a handle on the door face. If your switch sits flush with the door and needs no reach, you do not need the extension at all.
8) What shaft extension should I order for an Eaton rotary disconnect with an SH0 handle instead of the Square D GS2AE?
For an Eaton rotary disconnect operated by an SH0 or SH00 external handle, the Eaton rotary disconnect shaft extension in the R5/R9 series is the matching part. The Square D GS2AE is the equivalent accessory on the other side of the aisle, dedicated to 3-pole and 4-pole TeSys GS2 fuse switch-disconnectors covering 60A to 400A motor FLA. Identify which switch platform is already in the enclosure before choosing, since the two are not interchangeable.
9) Do I need a different shaft extension for a 4-pole GS2 switch than for a 3-pole one?
No. The Square D GS2AE shaft extension works with both 3-pole and 4-pole IEC/UL fuse switch-disconnectors across the TeSys GS2 range, so the pole count does not change the accessory you order. What does differ is the Eaton rotary disconnect shaft extension, which belongs to the R5/R9 series and pairs with SH0/SH00 handles rather than TeSys GS2 switches, so it is not an alternative for either pole configuration.
10) Will the GS2AE pass a RoHS submittal for a control panel build?
The GS2AE is RoHS Eur compliant and in scope, built mercury free and free of toxic heavy metals. Country of origin is Tunisia, which is the other line spec buyers usually need for a submittal package or a government bid.
