⚙️ Siemens 3KX7113-2AA00 – Black door-coupling operating mechanism with special-tool release for 3KA71/3KL71, sizes 1 and 2

The Siemens 3KX7113-2AA00 is a door-coupling operating mechanism with a release device operated by a special tool, in black, provided by Siemens as an accessory and spare part for 3KA71 switch disconnectors and 3KL71 switch disconnectors with fuses in sizes 1 and 2.

The mechanism is mounted on the door of the control cabinet and allows the switch disconnector installed inside to be operated from outside. The door interlock function prevents the door from being opened when the switch disconnector is in the ON position, protecting the operator from contact with live parts.

The special-tool release device allows authorised personnel equipped with the appropriate tool to override the interlock and open the door for inspection or maintenance work, in accordance with the safety procedures specified for the installation.

The weight is approximately 0.24 kg. The part number is now listed as discontinued by several distributors and is mainly in demand as a spare part for existing cabinets with 3KA71 or 3KL71 switch disconnectors.

❓ FAQ – Siemens 3KX7113-2AA00

✔️ What is the difference between the 3KX7113-2AA00 and the 3KX7112-2AA00?

Both are black door-coupling operating mechanisms for 3KA71 and 3KL71 sizes 1 and 2. The 3KX7113-2AA00 additionally has the special-tool release device, which allows authorised personnel to open the door even with the switch disconnector switched on; the 3KX7112-2AA00 does not have it.

✔️ What is the difference between the 3KX7113-2AA00, the 3KX7113-2AB00 and the 3KX7113-4AA00?

The 3KX7113-2AB00 is the EMERGENCY version of the same mechanism, while the 3KX7113-4AA00 is the black version for the larger sizes of the 3KA71 and 3KL71. The 3KX7113-2AA00 is the black version for sizes 1 and 2.

✔️ Is the 3KX7113-2AA00 compatible with my switch disconnector?

It is intended for 3KA71 switch disconnectors and 3KL71 switch disconnectors with fuses in sizes 1 and 2. The mechanism is used together with the extension shaft suited to the cabinet depth: before ordering, we recommend checking the correct combination of mechanism and shaft in the Siemens catalogue.

✔️ What are the most common problems with a door-coupling mechanism such as the 3KX7113-2AA00?

The most frequent problems include handles broken or cracked by impacts, worn interlock mechanisms that no longer hold the door, excessive play in the coupling with the shaft and release devices damaged by the use of unsuitable tools.

✔️ Can I receive the 3KX7113-2AA00 quickly?

Yes. If available in stock, the mechanism can be shipped quickly. Contact E-Repair Customer Care stating the part number and the type and size of the installed switch disconnector.
