This AC motor start and run capacitor is suitable for single phase 3/4HP (horsepower) motors by Sta-Rite, Berkeley, Pentek, Pentair with capacitor start Indution run (CSIR) control boxes.
Replacement for part number: U17-1423 , U17-1423-R and U17-2073 (note: U17-2073 is 330V, this 270V capacitor is compatible using it with the 230V control box)
3.35" height x 1.85" diameter.
59 MFD +20%/-0% (uF) 270VAC. Also described as 59 - 71UF . Some capacitors rated 330V which work the same in 230V power. discharge resistor attached 2 poles shown in photo.
Manufacturer part number: 091A059B270BD4X
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.
