The SELCO company history

SELCO has its origin in the Danish switchgear manufacturer Lauritz Knudsen A/S who in 1960 was the first in the world to protect a generator with robust, solid state electronics!

In 1968 Lauritz Knudsen A/S merged with another major switchgear manufacturer, NES. Through the next decade the company was named LK-NES. The early product range of generator control and alarm systems was marketed under the name NESELCO.

In 1984 SELCO A/S was established. To obtain the right environment for further growth, SELCO moved in 2005 to new and larger premises in Roskilde, Denmark.

This became head office for Administration, Research & Development, Production and Sales & Marketing. Already then SELCO had subsidiaries and many local partners, reaching customer relations in more than 80 countries all over the world.

SELCO was acquired by Littelfuse Inc. in 2011. Five years later, in March 2016, SELCO went through a management buy-out, and is now again privately owned, with headoffice in Roskilde, Denmark.
