ABSTRACT OF THE DISCLOSURE An overload circuit breaker has a housing and a tripping device supported in the housing and having a helically wound, current-carrying bimetal strip composed of two face-to-face arranged metal components situated, respectively, at the inside and at the outside of the bimetal strip. The bimetal strip has a tripping portion which executes a tripping motion as the bimetal strip undergoes deformation under the effect of heat generated by an excess current flowing through the bimetal strip. The bimetal strip is formed of two electrically serially connected, oppositely wound bimetal helices each having an outer end constituting the opposite ends of the bimetal strip. The bimetal strip is affixed to the housing at both of its opposite ends. Further, the bimetal helices each have an inner end connected to one another by a coupling part. The coupling part constitutes the tripping portion of the bimetal strip.
