LX WTC50 / WTC50M Circulation Pump Capacitor
The LX WTC50 / WTC50M Circulation Pump is a 0.25 kW single-phase spa circulation pump commonly found in pool & spa pumps setups. Its motor runs on a 7µF 450V motor-run capacitor in a CBB60-style can: here's the exact replacement and how to confirm it.

The LX WTC50 / WTC50M Circulation Pump spa circulation pump uses a 7µF 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 7µF (about 6.3-7.7µF) 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 WTC50 / WTC50M Circulation Pump needs 7µF (about 6.3-7.7µF), 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 - LX WTC50 / WTC50M Circulation Pump capacitor
What capacitor does the LX WTC50 / WTC50M Circulation Pump use?
A 7µF 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 LX WTC50 / WTC50M Circulation Pump?
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 (7µF).
