Patent ID: 7116194

Claim:
An electric pole for a low-voltage power circuit breaker, comprising: an insulating enclosure that has a lower wall, an upper wall, two side walls, a rear wall and a front wall; at least one arc chute; at least one fixed contact and at least one moving contact that can be mutually coupled/uncoupled; and a first electric terminal and a second electric terminal that are functionally associated with said fixed contact and said moving contact and allow electrical connection of the pole in input and in output, wherein said insulating enclosure comprises a first half-shell and a second half-shell which are mutually coupled along corresponding coupling surfaces and form a self-supporting structure, said first and second half-shells being shaped so as to form at least one compartment that is suitable to accommodate said fixed contact and said moving contact and said arc chute, and second and third containment volumes, which are arranged on mutually opposite sides with respect to said compartment and are suitable to accommodate respectively said first and second electric terminals, wherein respective first and second coupling means are arranged on and monolithically connected to the coupling surfaces of said first and second half-shells, said first and second coupling means being suitable to couple geometrically to each other so as to form said self-supporting structure.
