Built for Aussie worksites. These All Controls 450VAC P2 aluminium motor run capacitors keep single-phase motors running smooth in HVAC, refrigeration, and pump installs. If you’re chasing fewer call-backs and a tidy finish—too easy.
Key Features & Trade Benefits
- P2 safety class: Self-healing design for continuous duty—better protection on compressors and fan motors when the roof’s cooking.
- 450 VAC rating: Headroom for voltage spikes—more reliability on long runs and older sites.
- 1–100 µF range: Dial in the correct µF for stable RPM, lower amps, and quieter operation.
- Aluminium case: Tough against vibration and weather—ideal for rooftops and plant rooms.
- Clear µF labelling: Faster swaps and less guesswork when you’re time-poor.
Why This Product Matters
Up on a roof in 40-degree heat, you want gear that just works. Swap a weak run cap with the correct µF and you’ll often see smoother starts, cooler windings, and a happy client—fair dinkum difference. We’ve specced these for continuous duty with a P2 safety class and a 450VAC ceiling so you can fit once and move on. For systems that need both start and run support, pair with a proper start unit from our Start Capacitors—she’ll be right.
Pro Tip
Always match the µF printed on the OEM cap (±5% typical). If you’re not sure, test the old cap and the new install with a multimeter that reads capacitance. Grab one from our Multimeters range for quick on-site checks.
Compatibility & System Info
- For single-phase induction/PSC motors in HVAC fans, blowers, and some compressors.
- Suitable across systems using common refrigerants (e.g. R32, R410A, R134a). Capacitor selection is motor-specific, not refrigerant-specific.
- Voltage: 450VAC (use equal or higher voltage rating than OEM; never lower).
Local Jobsite Notes
Brisbane humidity, Sydney salt air, or dusty regional installs—these aluminium-case units hold up well to vibration and exposure. Fit-and-forget and onto the next call-out—bloody good.

FAQs
How do I choose the right µF?
Match the µF printed on the motor’s original capacitor (±5%). If the label’s unreadable, check the motor plate or the service manual. When in doubt, test with a capacitance-reading multimeter from our Multimeters.
Can I go higher on voltage?
Yes—equal or higher voltage than OEM is fine (e.g., replacing a 370VAC with 450VAC). Never go lower.
Do I need a start capacitor as well?
Some motors (PSC) only need a run cap; others use a separate start cap. If your system needs help getting off the line, add a unit from our Start Capacitors.
What about relays/overloads?
Pairing with a matched relay/overload can protect the motor and tidy up nuisance trips. See our Relay Overload Combo for a simple, field-ready solution.
