ABB Residual Current Circuit Breaker with integrated terminal blocks

The product shown is an electrical assembly featuring an ABB-branded residual current circuit breaker (RCCB) or similar modular protective device, pre-wired with DIN-rail mounted terminal blocks and cable glands inside a protective enclosure. ABB is a pioneering technology leader that works closely with utility, industry, transportation, and infrastructure customers.

The brand has deep roots in European engineering, formed by the 1988 merger of Sweden's ASEA and Switzerland's BBC (Brown, Boveri & Cie). While ABB operates a global manufacturing network, many of its modular DIN-rail components and circuit protection devices are manufactured in Europe, particularly in Italy and Germany. Today, ABB is a publicly traded multinational corporation headquartered in Zurich, Switzerland, serving as a global leader in electrification and automation.
