ABB circuit breakers for direct current applications
Currently, direct current is used primarily in urban transport like trolleybuses, trams and underground railways, with a supply voltage of 600 V or 750 V, up to 1000 V. The use of direct current is not limited only to vehicle traction. Direct current represents a supply source for the auxiliary circuits on board vehicles as well. In this case, ac-
