  • the mechanism is arranged so that it can be placed in the housing by being arranged above and in front of the coil by presenting one, and preferably two springs which are arranged in housings of the housing to be able be tensioned, preferably by extension after placement through corresponding lights of the housing after assembly and fixing of two half-shells forming the housing. In this way the springs do not exert any stress on the mechanism during installation in the housing.
  • the invention also relates to a method of mounting this single-pole circuit breaker characterized in that one carries out, separately, said three sets, so as to be able to store separately. Sets having different nominal characteristics, then in that the 'said assemblies are mounted in the housing.
