Moeller Electric's history is dotted with milestones rooted in innovations that have greatly influenced the electrical industry and, in many ways, revolutionized its development. What began with the design of the first small, oil-immersed contactor at the beginning of this century remains valid today with a whole new generation of products. Some of the most notable technological achievements in the company's history are:

Franz Klöckner founds a switchgear production company in Cologne, Germany.

Greater customer proximity is achieved thanks to decentralising the sales organisation. Assembly-line production is introduced at the Moeller works.


Improvement of oil-immersed contactors using new materials. Motor-protective circuit-breakers and bimetal relays are added to the product range.


Contactor relays are mass produced at six factories. The 'long weekend' is introduced.


Production of the first switchgear devices with a service life comparable to that of the machines in which they are deployed.

Moeller starts to deliver switchgear to electrical wholesalers and undergoes a change in name to Klöckner-Moeller. Felten & Guilleaume Carlswerk is founded in Kleedorf, Lower Austria.
