Electric pole for a low-voltage power circuit breaker, and associated circuit breaker

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