<p>Single-phase circuit breaker has a switching mechanism (2), which can be actuated by at least one overload release element (1). A wedge-shaped adjustment element (4) between the overload release element (1) and a yoke (3) acting on the switching mechanism (2) is permanently attached to an intermediate guide part (6) via an elastically flexible spring (13) and that the intermediate guide part (6) is displaceably held in the housing of the circuit breaker in the working direction of the overload release element (1). The guide part is mounted in the switch housing so as to be movable in the working direction of the overload protection element. At least one, preferably two, further switches can be coupled to the first switch so that an overload on one switch causes isolation by all switches.</p> |
