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: U17-1425 , U17-1425-R , U17-2065 (330V)
Manufacturer part # 091A105B270BD4X
3.35" height x 1.85" diameter.
105 MFD +20%/-0% (uF), also described as 105-126UF, 270VAC, Some capacitors rated 330V which work the same in 230V power. discharge resistor attached 2 poles shown in photo.
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.
I had someone cross the wires up in my old well pump. This was a direct replacement and has been working well for a few months now. I would buy it again. Shipping was fast too.
