Learn more by watching our AC Direct CAP20UF | Motor Run Capacitor 20uF video.
The AC Direct CAP20UF is a motor run capacitor rated 20uF at 450VAC, supplied for single-phase motor circuits in air conditioning and HVAC equipment. It holds capacitance within plus or minus 5 per cent of nominal and operates on both 50Hz and 60Hz supplies. The CAP20UF is declared to Safety Class S2 and temperature class 40/85/21. Sparky Direct lists it under Circuit Protection as a service replacement part.
A single-phase motor that hums, trips its overload, or fails to reach speed usually points to a failed run capacitor rather than the motor itself. Bulged cans, split cases and terminal leakage are the usual findings on a breakdown call, and the remedy is a like for like replacement. The CAP20UF carries a 20uF rating at 450VAC, which suits equipment specified at that value. Matching capacitance and voltage matters more than brand preference on a service job.
HVAC and electrical contractors carry the common run capacitor values as van stock, because a breakdown call depends on having the part on board. The CAP20UF is a minor component on a substantial callout, and the changeover is short work once the equipment is isolated. The 450VAC rating accommodates both 50Hz and 60Hz equipment, which keeps van inventory manageable across manufacturers. A one-year warranty applies from the invoice date.
The CAP20UF is not rated for direct current circuits and is not a substitute where a motor calls for a start capacitor or a different microfarad value. It carries no declared IP rating, so it belongs inside the equipment enclosure rather than in an exposed or wet position. Applied voltage must not exceed 450VAC.
(CAP20UF)
The CAP20UF is a motor run capacitor rated 20uF at 450VAC, held within plus or minus 5 per cent of nominal capacitance. It operates on 50Hz and 60Hz supplies, so it suits single-phase motor circuits on both Australian and imported equipment.
This motor run capacitor is declared to Safety Class S2 and to temperature class 40/85/21, the climatic category covering its operating temperature range and damp heat exposure. Confirm the classification suits the application with the equipment manufacturer or a licensed installer before fitting.
Electrical and HVAC products sold by Sparky Direct are intended for installation by licensed and appropriately qualified professionals under the relevant Australian Standards. Warranty cover is void where a product is not installed by a licensed electrician, so the work belongs with a qualified installer.
Read the value printed on the failed capacitor or the motor nameplate. The CAP20UF suits circuits calling for 20uF at 450VAC or less. Voltage may be equal or higher than the original rating, but capacitance should match. Confirm selection with a licensed installer before purchase.
A run capacitor stays in circuit the whole time the motor turns, holding the phase shift on the auxiliary winding for continuous operation. A start capacitor gives a short boost during run-up and then drops out. The CAP20UF is a run capacitor, not a starting capacitor.
Common symptoms are a motor that hums without turning, comes up to speed slowly, draws high current, or trips its overload. Physical signs include a bulged can, a split case, or leakage around the terminals. Diagnosis with a capacitance meter confirms the fault.
Warranty runs for one year from the invoice date for both domestic and commercial use, with the warranty method being return to Sparky Direct. Warranty is void if the product is not installed by a licensed electrician. Proof of purchase is required for any claim.
The AC Direct CAP20UF is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
