Abstract

There is a circuit breaker, which is assembled from a plurality of individual circuit breakers 22 in a shell method of construction 35, 36, which, in the event of an overload on only one individual circuit breaker 22, isolates all terminals by coupling the individual circuit breakers and in which each individual circuit breaker 22 is constructed completely in its shells 35, 36, including the overload release element and the switching mechanism. In this case, it is desired to complete the circuit breaker in a simple manner to form a motor circuit breaker with current-range setting. This is achieved in that a motor circuit breaker current-range setting device is provided which has an operating device 26 and a current scale 30 allocated thereto, and in that this one adjusting device engages with an adjusting element 19 into each individual circuit breaker 22. A single current-range setting device is provided which is modified in such a manner that it acts simultaneously on each individual circuit breaker. <IMAGE>
