This AC motor start and run capacitor is suitable for single phase 1/3HP (horsepower) motors by Sta-Rite, Berkeley, Pentek Pentair with capacitor Induction run (CSIR) control boxes.
Replacement part number: U17-1422 , U17-1422-R
3.35" height x 1.85" diameter.
43 MFD +20%/-0% (uF) 270VAC.
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 rangeor or electrolyte leaking is observed.
