Where can I find trip curves for the QO-GFI, QO-EPD and QO-EPE breakers?
Where can I find trip curves for the QO/B-GFI, QO/B-EPD and QO/B-EPE breakers?
QO/B-GFI, QO/B-EPD and QO/B-EPE 1P, 2P and 3P Miniature Circuit Breakers
This applies to all QO/B-GFI, QO/B-EPD and QO/B-EPE 1P, 2P and 3P breakers
QO/B-GFI 3P and QO/B_EPD and QO/B-EPE trip curves can not be found.
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.
Use 910-1 for 15A 1P
Use 910-2 for 20A 1P
Use 910-3 for 15, 20 and 25A 2P and 3P and 25A 1P
Use 910-4 for 30A 1P, 2P and 3P
Use 910-5 for 40 to 60A 2P, 40 to 50A 3P
