The invention relates to a full-protection circuit breaker (1) having a line-protection circuit breaker (2) and a residual-current-operated component (4) which can be fitted thereto. A first switching mechanism is located therein, comprising a first switching toggle (6) for operation of a first latching mechanism, which is accommodated in the residual-current-operated component (4) and has at least one first latching point (8). A second switching mechanism is provided in the line-protection circuit breaker (2) comprising a second switching toggle (16) for operation of a second latching mechanism (14), which is accommodated in the line-protection circuit breaker (2) and has at least one second latching point. The first and the second latching mechanisms (8, 14) are coupled by means of a first coupling element (10) such that, when the first latching point is unlatched, the second latching point is also unlatched and in the process at least one contact point of the line-protection circuit breaker (2) is opened, and that the second latching mechanism can be reconnected by means of the second switching toggle only when the first switching toggle has been pivoted through a predeterminable lead angle from its disconnected position in the direction of its connected position. The characterizing feature of the invention is that the first and the second switching toggle (6, 16) are coupled by means of a second coupling element (18, 181, 182), wherein the second coupling element acts on the first switching toggle (6) with respect to the second switching toggle (16), pivoting through the predeterminable lead angle in the direction of its connected position.
