Abstract
A full-protection circuit breaker has a line-protection circuit breaker and a residual-current-operated component which can be fitted thereto. A first switching mechanism, located therein, includes a first switching toggle for operation of a first latching mechanism, which is accommodated in the residual-current-operated component. A second switching mechanism, provided in the line-protection circuit breaker, includes a second switching toggle for operation of a second latching mechanism, which is accommodated in the line-protection circuit. The first and the second latching mechanisms are coupled by means of a first coupling element. The first and the second switching toggle are coupled by means of a second coupling element, wherein the second coupling element acts on the first switching toggle with respect to the second switching toggle, pivoting through the predeterminable lead angle in the direction of its connected position.
