AUTOMATIC BREAKER IN LITHUANE CASE AND METHOD OF ITS ASSEMBLY

摘要

A moulded case circuit breaker is described comprising at least a first contact branch (C1) comprising at least a first contact element (P1) and at least a first support element (S1) of the first contact element (P1), at least a first connection terminal (T1) electrically connected to, or integrated into, the first support element (S1); - an actuating mechanism (15) of the first support element (S1) adapted to move the latter so that the first contact element (P1) can be moved from a rest position to a working position and vice versa; - a first case (10) housing and supporting the first contact branch (C1) and the actuating mechanism (15); - a second contact branch (C2) comprising at least a second contact element (P2), adapted to be contacted by the first contact element (P1) when this is in the working position, at least a second support element (S2) of the second contact element (P2) and at least a second connection terminal (T2) electrically connected to, or integrated into, the second support element (S2); - a second case (20) coupled to the first case (10) housing and supporting the second contact branch (C2); - at least one fastening element (31, 32) adapted to couple and maintain the first (10) and the second (20) case integral to each other.
