We have developed a range of retrofit solutions for aging switchgear from AEG. They serve to upgrade, renew and modernise old switchgear with AEG circuit-breakers. Here, we at SZM look for a solution with a modern switching device from Siemens or ABB that fits exactly in the place of the old switch, replacing the "heart" of the installation, so to speak. The switchgear remains the same, but by replacing it we extend its operating life and bring it up to the current state of the art.

• AEG RM1 M 406/10N ⇒ Retrofit with ABB VD4 (7.2 kV, 630 A, 25 kA):

All the above-mentioned solutions for renewal and modernisation can, of course, also be adapted if necessary or completely new solutions can be developed. For this purpose, we have an in-house engineering department with experienced designers and technical draughtsmen.

If you would like to research a suitable modernisation solution on your own, you can do so directly in our SZM Retrofit Configurator with just a few entries!
