BELUK's History


1956 BELUK GmbH was established in Munich, Germany by the German „Münchener Aktiengesellschaft für Licht- und Kraftversorgung“ (LUK), the German „Bayerische Elektro- und Gasgeräte-Vertriebs GmbH“ (BEG) and the british „Londex Ltd“. Today's shareholders are N-ERGIE Aktiengesellschaft and Frankenluk AG and a group of private investors.

At the beginning BELUKs goals were design, manufacturing and sales of Power Factor Controllers. Since then the manufacturing facilities were located in the Bavarian city of Schongau, the headquarters moved from Munich to Schongau in 2001.

Today BELUK rises to the new challenges of ecologic and efficient power distribution.

Modern capacitive and inductive power compensation banks equipped with utmost BELUK devices take care for economically optimised and environmentally friendly operation of power industrial and distribution networks. BELUK fast acting thyristor switches allow design of highly dynamic compensations for rapid changing network conditions. BELUKs OEM products are widely used by renowned manufacturers of reactive power compensation banks.

BELUK resigns to use SF6 as insulation gas for any of its switchgear product lines and lead in the soldering process of the electronic production line. Of course BELUK complies to latest standards of RoHS and REACH and supports the guidelines set in “conflict minerals act”.
