In 1947, Renato GHISALBA set up his company in Turin, marking the beginning of an activity  destined to leave its mark. Originally conceived as a workshop specialising in repairing Fiat machinery compromised by the events of World War II, GHISALBA has evolved and adapted to the changing times. Today, the company stands out as a leader in the design and production of one of  the widest range of three-pole and four-pole contactors available all over the world, with capacities up to 2000A. The transformation of GHISALBA  from a little workshop to a strong company known all over the world is a  path of excellence and constant effort in quality and  technology development.
