Abstract
A trip system for a circuit breaker having a calibration system is disclosed. The calibration system includes a retainer, a tripping member responsive to an electric current, an actuator retained by the retainer, a spring adjuster adjustably engaged with the actuator and the tripping member, and a bias spring disposed for biasing the actuator in a first direction. Movement of the spring adjuster absent movement of the actuator and the tripping member results in a change in the bias spring force and no change in the position of the tripping member, and movement of the tripping member absent movement of the spring adjuster results in a change in the position of the tripping member and no change in the bias spring force.
