ABSTRACT:
An electric pole for a low-voltage power circuit breaker, comprising an insulating enclosure (20, 30) 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 (8) and at least one moving contact (9) that can be mutually coupled/uncoupled, and a first electric terminal (10) and a second electric terminal (11) that are functionally associated with the fixed contact and the moving contact and allow electrical connection of the pole in input and in output, its particularity consisting of the fact that the insulating enclosure comprises a first half-shell (20) and a second half-shell (30) which are mutually coupled along corresponding coupling surfaces and form a self-supporting structure, the first and second half-shells being shaped so as to form at least one compartment (12) that is suitable to accommodate the fixed contact and the moving contact and the arc chute, and second (13) and third containment volumes (14), which are arranged on mutually opposite sides with respect to the compartment and are suitable to accommodate respectively the first and second electric terminals.
