ABB is a Swiss-Swedish multinational corporation headquartered in Zürich, Switzerland, operating mainly in the power and automation technology areas.

ABB is one of the largest engineering companies as well as one of the largest conglomerates in the world. ABB has operations in around 100 countries, with approximately 117,000 employees, and reported global revenue of $31.8 billion for 2009.

ABB resulted from the 1988 merger of the corporations ASEA (Allmänna Svenska Elektriska Aktiebolaget, Swedish) and Brown, Boveri & Cie (Swiss); the latter had absorbed the Maschinenfabrik Oerlikon in 1967. CEO at the time of the merger was the former CEO of ASEA, Percy Barnevik, who ran the company until 1996.

ABB's history goes back to the late nineteenth century. ASEA was incorporated by Ludwig Fredholm in 1883 and Brown, Boveri & Cie (BBC) was formed in 1891 in Baden, Switzerland, by Charles Eugene Lancelot Brown and Walter Boveri as a Swiss group of electrical companies producing AC and DC motors, generators, steam turbines and transformers.

ABB offers a wide range of main distribution boards for every application. The product range ArTu is a modular conception, distinguished by multiple combination and customised construction possibilities.

For the final part of electrical installations, ABB has a vast range of junction boxes, empty enclosures and command devices which are also designed for installation with protective rigid conduits. Their sturdy construction and special protection features mean that these devices and enclosures can be used in all types of installation.
