Abstract

A two-pole circuit breaker has an internal rotating trip bar that causes a second pole to trip (i.e., interrupt power) in response to a first pole tripping. A first pole may trip when the two-pole circuit breaker senses an electrical fault in the first pole. The tripping of the second pole in response to the first pole tripping may be referred to as common tripping. The trip bar may be connected to a tripping mechanism in each pole and may have interface features that result in less force required to trip the second pole, greater trip bar design tolerances, and/or ultimately more reliable common tripping. Methods of assembling a two-pole circuit breaker are also provided, as are other aspects.
