A circuit breaker subassembly (50) is disclosed. The subassembly includes a base (475), an operating mechanism (65), a one-piece non-conductive rotor (105) disposed within the base (475), and a plurality of sets of contact arms (190) supported by the rotor (105). The rotor (105) is disposed in operable connection with the operating mechanism (65) and includes a rotational degree of freedom relative to the base (475) with portions of the rotor (105) disposed between each set of the plurality of sets of contact arms (190) to define separation portions (450). The operating mechanism (65) includes a frame (310) disposed within the base (475), a cradle (340) in pivotal connection with the frame (310), an upper link (350) in pivotal connection with the cradle (340), and a lower link having a first end (410) and a second end (415), the first end (410) in pivotal connection with the upper link (350) and the second end (415) in pivotal connection with the rotor (105) at the separation portions (450). |
