The run capacitor for the DAB Jet 251
A 40 µF (40 uF / 40 MFD) 450 VAC CBB60 motor-run capacitor with core leads, sized for the DAB Jet 251 pump. Single-phase pump motors like this one run with the capacitor permanently in circuit, so a weak capacitor shows up as a pump that struggles to start or runs hot.
Signs the Jet 251 capacitor has failed
- the motor hums but won’t start, or only starts when the shaft is spun by hand
- the pump trips the breaker or overload shortly after starting
- the motor runs hot and slow, or the old capacitor is bulging or leaking
A replacement must match the µF value (±5%) and be rated at least the voltage of the original. This one is rated 450 VAC, fine for a DAB Jet 251 on a 230 V supply.
The same capacitor rating is used in the DAB Jet 300, DAB K14/400, DAB K36/100, DAB K55/50, Ebara DWO 200M.
Before you order
Check the old part before fitting: match the µF printed on your old capacitor.
The value is printed on the side of the old capacitor as µF, uF or MFD.
