I actually used to calibrate and QC high end breakers for a well know company who's name is a letter and a shape. To pass QC the breakers would need to heat trip when run at 135% Amps between roughly 20-45 minutes. Both too fast and too slow were a failure. The actual range was a bit different by Ampage which I never quite understood. |
