Abstract

The present invention relates to a single-pole circuit breaker, wherein the mechanic components of the snap mechanism, such as the manual operating member (8), the latching cradle (12) and the movable contact carrier (29) have a flattened shape so that they are assembled in a superimposed position thus allowing the reduction of the size of the circuit breaker, all said components being shaped such in a way that they may be easily produced by simple blanking, without requiring further machinings and still assuring the best intervention chances particularly in overload or short circuit current conditions.
