Summary:A circuit breaker crossbar assembly (18) includes a crossbar (19) having a first and second segment (32, 34), the first and second segment (32, 34) each operatively coupled to a respective moveable contact arm assembly (38, 40). Also included is a coupling segment (44) disposed between the first and second segment (32, 34), the crossbar (19) and the coupling segment (44) rotatable about an axis. Further included is at least one support assembly (50) operatively coupled to the coupling segment (44). The support assembly (50) includes a bushing (52) coupled to the coupling segment (44) and rotatable with the crossbar (19) and the coupling segment (44). The support assembly (50) also includes a support bracket (54) configured for affixation to a stationary structure (70) and disposed adjacent to the bushing (52), the bushing (52) rotatable relative to the support bracket (54). The support assembly (50) further includes a fixing bracket (56) engaged with the support bracket (54) and disposed adjacent to the bushing (52), the bushing (52) rotatable relative to the fixing bracket (56).
