The DAB K36/100 is listed with a 40 µF (40 uF / 40 MFD), 450 VAC run capacitor. This CapacitorsNZ replacement is a CBB60 motor-run capacitor with core leads, to suit the single-phase K36/100 motor. Before ordering, read the value printed on your old capacitor: if it says 40 µF, this is the right one; if it shows a different figure, order that value instead.
Choosing the right capacitor for the DAB K36/100
Two numbers matter. The capacitance in µF (sometimes printed uF or MFD) must match the old capacitor, within its stated tolerance. The voltage rating must be the same or higher; a 450 VAC capacitor is a standard rating for a single-phase motor on a 230 V supply.
Core ls means the capacitor has wire tails rather than spade tags, so look at how your old one connects before swapping. Go by the µF printed on the capacitor itself, not the pump’s model name alone. The DAB K-series capacitor guide covers the range.
Signs the K36/100 capacitor has failed
A single-phase motor like this one keeps its run capacitor in circuit the whole time it runs, so a weak or dead capacitor affects both starting and running.
- The motor hums but won’t turn, or only starts if the shaft is spun by hand.
- The pump trips the overload or breaker soon after starting.
- The motor runs hot and sluggish, or the old capacitor is swollen, cracked or leaking.
Other pumps that use a 40 µF 450 VAC capacitor
The same rating is listed for the DAB Jet 251, DAB Jet 300, DAB K14/400, DAB K55/50 and Ebara DWO 200M. It is also sold without a model name as our 40 µF 450 V CBB60 capacitor.
Swapping it safely
Turn the pump off at the switchboard and unplug it. A capacitor can hold a charge after the power is off, so discharge it safely before touching the leads. Photograph the wiring first, connect the new capacitor the same way and clamp it firmly in place. If you are not confident working on mains wiring, have an electrician do it.
Before you order
Check the old part before fitting: match the µF printed on your old capacitor.
