Abstract: A circuit breaker includes a plurality of pole assemblies, each having a movable contact and a stationary contact. A bellcrank assembly is associated with each pole assembly. Each bellcrank assembly includes a bellcrank lever including a cylindrical body and at least one radially extending arm. The radially extending arm is mechanically interrelated with the movable contact so that rotation of the bellcrank lever selectively causes the movable contact to engage or disengage the stationary contact. At least one of the bellcrank lever radially extending arms is relatively more flexible than the other bellcrank lever radially extending arms.
