20130076479Tool and Calibration Machine for Calibrating a Thermal Trip Apparatus of a Circuit Interrupter, and Improved Method - An improved calibration machine for calibrating a thermal trip apparatus of a circuit interrupter employs a tool having an elongated shank and a pair of engagement elements. The engagement elements are engageable with a support that carried a bimetal element. The engagement elements can deform the support in opposite directions to either increase or decrease the thermal trip setting of the thermal trip apparatus. If the support is over-deformed in one direction, it can be deformed in an opposite direction to enable a circuit interrupter whose thermal trip apparatus has been deformed beyond a desired target thermal calibration setting to be deformed in an opposite direction to reach the desired target thermal calibration setting.03-28-2013
