DAB ACTIVE EI 30/50 M Capacitor

The DAB ACTIVE EI 30/50 M is a single-phase pressure system / booster set commonly found in well & domestic pumps setups. Its motor runs on a 12.5µF 450V motor-run capacitor in a CBB60-style can: here's the exact replacement and how to confirm it.

Pump type: pressure system / booster set
Motor: single-phase
Run capacitor: 12.5µF · 450V · CBB60
Application: Well & domestic pumps
Also sold as: ACTIVEEI30/50M, ACTIVE EI 30/50M-N.8
Fitment source: Manufacturer-documented, our pump-spares records

Manufacturer-documented12.5µF · 450V

The DAB ACTIVE EI 30/50 M pressure system / booster set uses a 12.5µF 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 our pump-spares records. Match the replacement to 12.5µF (about 11.3-13.8µF) at 450V or higher; the checklist below covers how to confirm it against your own capacitor.

We don't currently stock this exact value (12.5µF 450V). Browse the closest matches or ask us. We can usually source it.

How to be sure you get the right one

µF must match: the ACTIVE EI 30/50 M needs 12.5µF (about 11.3-13.8µF), 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 - DAB ACTIVE EI 30/50 M capacitor

What capacitor does the DAB ACTIVE EI 30/50 M use?

A 12.5µF 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 DAB ACTIVE EI 30/50 M?

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 (12.5µF).
