This AC motor start capacitor is suitable for single phase submersible pumps by Sta-Rite, Berkeley, Pentek Pentair with capacitor start and capacitor run (CSCR) control boxes.
It is fully compatible for replacing those capacitors with part number: U17-1428, U17-1428-R , 091A208B330CE7X
4.25" height x 2.15" diameter.
208-250UF, 330VAC, also described as 208 MFD +20%/-0%. Discharge resistor attached 2 poles shown in photo.
MFD, MF or UF are all the same meaning - Micro Farad.
The start capacitor in a motor control box is considered a consumable part. Capacitors tend to lose capacitance over time and/or use, and need to be replaced when the capacitance drops 10% below the described range or electrolyte leaking is observed.
