Issue:
Where can I find trip curves for the QO/B-GFI, QO/B-EPD and QO/B-EPE breakers?
Product Line:
QO/B-GFI, QO/B-EPD and QO/B-EPE 1P, 2P and 3P Miniature Circuit Breakers
Resolution:
Use the Class 910 trip curves for QO/B-GFI breakers. Though EPD and EPE breakers are not listed on the curve, their trip characteristic is identical to the QO/B-GFI. These curves also apply to the 3P versions of the breakers as well, even though they are not listed on the curve.
