OFFCUP CBB60 20μF Running Capacitor, 450V AC

The OFFCUP CBB60 running capacitor is listed at 20μF and 450V AC for starting and running single-phase motors. Its stated 50/60Hz rating and 4-pin connection may suit a compatible repair, but match capacitance, voltage, dimensions and terminals to your equipment before fitting.

At a glance

Listed for starting and running single-phase motors on 50Hz/60Hz AC systems.
The title specifies four pins and a screw-bottom cylinder design. The details table instead lists a rectangular shape and through-hole mounting.
The manufacturer lists air compressors, water pumps, cleaning equipment, washing machines, fans and other motors as possible applications.

Pros and cons

Pros

The 20μF and 450V AC ratings are clearly stated for checking against a replacement specification.
The stated 50/60Hz rating covers both common AC frequency categories named in the listing.
A four-pin connection is specified in the title, which helps buyers compare terminal style.

What to know before buying

Listing details to confirm

The listing is inconsistent about dimensions and form: the title says 75x40mm and describes a cylinder bottom with screw, while the details give a rectangular shape and the feature text states 10x4.1 cm (length*depth). The title specifies 4 pins, but terminal details and the stated mounting type are not fully reconciled. Confirm the physical size, terminal layout and fit against the original part before buying. The 450V capacity is described as a rated voltage in one place and a maximum voltage in another.

Running capacitor

Who is it for?

A good fit for

Replacing a capacitor in a compatible single-phase motor where 20μF, 450V AC, 50/60Hz and the physical connection match the original.
Repair tasks involving listed applications such as air compressors, pumps, cleaning machines or fans.

Less suited to

Buyers who cannot confirm the original capacitor's capacitance, voltage rating, dimensions and terminal arrangement.
Applications needing a different capacitance or an explicitly verified fit for a particular appliance model.

Aggregate ratings are mostly five-star, with a smaller spread across lower star categories. This gives a generally favourable overall impression but does not identify what buyers liked or disliked, or establish fit in a particular motor. For this replacement part, the stated electrical rating is useful, while the inconsistent size and connection descriptions make checking the original capacitor especially important.

Frequently asked questions

What electrical rating is listed?

The listing gives 20 Microfarad, 450 Volts (AC) and 50/60Hz. Match these ratings to the equipment's original capacitor.

Will it fit my motor?

Fit is not established for a specific motor. The title states four pins, while the listing's mounting and size descriptions are inconsistent. Check the original part's dimensions and terminals.

What applications does the manufacturer name?

The listing names single-phase motors, air compressors, water pumps, cleaning equipment, washing machines and fans among its examples. These claims do not confirm compatibility with a particular device.
