Abstract:
1. A low-voltage circuit breaker comprising: a containment structure; a control mechanism; a plurality of circuit breaking poles, each of which comprises a housing containing a sealed ampoule that in turn contains at least one fixed contact and at least one moving contact, which can be mutually coupled and uncoupled, said housing comprising a first side and a second side that define an interior containing said ampoule, an outer side wall on said first side being complementary to and associable with an outer side wall of said second side, said poles being located side-by-side to form a set of poles complementary to at least a part of said containment structure; and operative connection means between said control mechanism and said poles; said control mechanism comprise a first drive shaft operatively connected to said operative connection means converting the rotatory movement of the drive shaft into a substantially linear translatory movement of the moving contact along a predefined axis, and comprise, for each pole a drive lever fixed to the drive shaft and operatively connected to the moving contact, and comprise a first connecting rod connected to a first connection point on said drive lever and to a first carriage for operating said moving contact; said first carriage comprises a sloping surface operatively coupled to the corresponding moving contact and suitable for converting a translatory movement of said first carriage into a translatory movement of the moving contact along a predefined axis.
