Abstract (en)
[origin: EP2634788A1] The circuit breaker has a latch (1) including a switching mechanism (2) for opening and closing a switching contact. An unlatching mechanism (3) changes a tensioning element from a tensioned state to a largely untensioned state based on a tripping signal to open the switching contact. The tensioning element is linked to a tensioning lever (5) including a locating surface on which a locking pawl (8) of the unlatching mechanism bears in the tensioned state of the tensioning element. The locating surface is curved in a direction of the locking pawl and movably arranged relative to the lever.
