Buying Guide

Match capacitance to motor spec

Select a capacitor with the microfarad (µF) rating specified on the motor nameplate to ensure correct starting torque and avoid overheating

Confirm rated voltage

Choose a capacitor rated for the system voltage (110–125V or 220–250V) to prevent premature failure and ensure safe operation

Check duty and construction

Use capacitors labeled for motor start duty or CD60 construction for brief, high-current starts instead of continuous-run types

Prioritize physical fit and terminals

Verify housing size and terminal style to fit the motor compartment and wiring layout without modification

Consider spare and pack options

Buying multi-packs or common replacement values reduces downtime, especially for pumps in continuous or critical service
