ABSTRACT:
The reset lever on a circuit breaker undervoltage relay is actuated by translating arcuate movement of a handle arm pin as the circuit breaker handle is moved to the off position into rotation of the reset lever through a complaint interface lever that is stiff enough to actuate the reset lever, but flexible enough to accommodate for overtravel of the handle arm pin when the circuit breaker is reset and for the stackup of tolerances in the operating mechanism.
