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 , U17-1430 , U17-1425-R , U17-2065 (330V). Some control box's capacitor is 270V withstand voltage but eventually will all replaced with 330V as the manufacturing cost is the same. They are interchangeable. We now stock the 330V version.
Manufacturer part # 091A105B330BD4X , 091A105B270BD4X or CMCI 105MFD+20%/-0%
3.35" height x 1.85" diameter.
105 MFD +20%/-0% (uF), also described as 105-126UF, 330VAC or 270VAC. 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.
This was an exact replacement for what I needed. Good price. Excellent service.
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.
