ABB Group is a Swedish-Swiss technology company, that operates in the fields of electrification and automation. The company was formed in 1988 from the merger of two electrical engineering companies, ASEA of Sweden and Brown, Boveri & Cie of Switzerland. Incorporated in Switzerland as ABB Ltd, and headquartered in Zurich, it is dual-listed on the Nasdaq Nordic exchange in Stockholm, Sweden, and the SIX Swiss Exchange in Zurich, in addition to OTC Markets Group's pink sheets in the United States. For 30 years, it has been a part of the Fortune Global 500. Employees of ABB and its predecessor companies developed several technologies for generating, transmitting, and distributing electricity, as well as for enabling industrial automation. One is the miniature circuit breaker, invented by Hugo Stotz, which protects against fires and is found in almost every home. Predecessor ASEA was the first company to introduce a microprocessor into an industrial robot and it helped to develop the electric propulsion system "Azipod", which improved manoeuvrability by locating the propulsion system outside the hull.
