Abstract (en)
[origin: EP1065683A2] A low-voltage (LV) circuit-breaker has a housing comprising of a rear-wall and a front-part, and containing a contact system which has at least one, ideally two, approximately parallel, withdrawable connection rails or bars, for connecting the contact system to an external circuit. The connection rails extend through window apertures located in the rear wall of the housing and are positioned in the housing by spacers. One of the connection rails serves as a carrier for a positionally-fixed switching contact and a arcing horn, while the other connection rails are joined via a hinged- or flexible-conduction arrangement to a moveable switching contact of the switching contact system. The connecting rails (2;3) are shaped so that the spacers (12-15) are each integrated as an integral part into the connection rails (2;3). The cross-section of the current-carrying part of each connection rail is selected to correspond to the required rated current of the LV circuit-breaker (1).
