SEG History

1969

600 million energized people watched one of the greatest events in human history on television: the moon landing. Similarly, for SEG Electronics, an exciting journey into a successful future began with a small step in a garage in Krefeld: its founding as “Schaltanlagen-Elektronikgeräte GmbH.” Discover here how the story continued.

what our customers say:

The new WIC g2 protection relay from SEG is the successor to the successful WIC1 relays, which we started using in our Xiria, the compact Air GIS Ring Main Unit, since it’s introduction in 2002. This self powered relay now provides great additional options to comply with today’s digital demands.

Sezar Atakay, Front End Lead Application Engineer & Coordinator

An easy and short-term 1:1 replacement in existing projects ran absolutely smoothly, and the functionality compared to Generation 1 has also been extensively expanded.

Holger Lauer, Offer Management

The WIC1 g2 protection relay from SEG is very user-friendly, compact, and reliable.
