Application
This start capacitor is intended for use in Rheem and Ruud HVAC systems requiring a 270–324 MFD, 330 VAC round start capacitor. Start capacitors are used to provide the extra electrical boost needed during motor startup and are then switched out of the circuit once the motor reaches running speed. Always verify compatibility with your specific equipment model before installation.
Installation Notes
- Discharge capacitor fully before handling — stored charge can cause serious injury
