Davey PowerMaster PM450 Capacitor

The Davey PowerMaster PM450 is a 1.8 kW single-phase pool pump commonly found in pool & spa pumps setups. Its motor runs on a 30µF 450V motor-run capacitor in a CBB60-style can: here's the exact replacement and how to confirm it.

The Davey PowerMaster PM450 pool pump uses a 30µF 450V motor-run capacitor (CBB60-style): it's the part that helps the single-phase motor start and keep running smoothly. We source this value from manufacturer / supplier documentation. Match the replacement to 30µF (about 27-33µF) at 450V or higher; the checklist below covers how to confirm it against your own capacitor.

How to be sure you get the right one

  • µF must match: the PowerMaster PM450 needs 30µF (about 27-33µF), within ±5% of the label. Too low and the motor won't start; too high and it runs hot.
  • Voltage can go up, never down: a 450V (or higher) cap is correct here; a 450V part safely replaces a 370V or 440V one. Don't fit below 450V.
  • Check the terminal + size: make sure the new cap physically fits the housing and the connections match (or use a spade adapter).
  • When in doubt, read your old cap: the printed µF and voltage on the part you're replacing is the final word.

Common questions - Davey PowerMaster PM450 capacitor

What capacitor does the Davey PowerMaster PM450 use?

A 30µF 450V motor-run capacitor (CBB60-style). Always confirm against the rating printed on your existing capacitor before ordering.

Can I fit a higher-voltage capacitor in the Davey PowerMaster PM450?

Yes, voltage can be equal or higher, never lower. A capacitor rated 450V or above is fine (450V is the usual choice), as long as the µF still matches (30µF).
