RUN CAPACITORS (MOTOR RUN THREADED CAPACITOR WITH 8M BOLT)

Built for Aussie job sites, these All Controls 450 VAC Motor Run Capacitors come with a threaded M8 mounting bolt for a tidy, rock-solid fit. Ideal for licensed techs and apprentices who want fewer call-backs, smoother starts and stable RPM, too easy.

Key Features & Trade Benefits

• Threaded M8 bolt mount → fast, secure install on brackets and within housings; no fiddly straps on rooftops.
• 450 VAC rating → headroom for spikes and brownouts; keeps motors running steady on older sites.
• P2 safety class → self-healing design suited to continuous duty; more uptime on fan motors and compressors.
• 4–60 μF range → pick the exact μF to match nameplate specs; stable torque and lower amps.
• Aluminium case → tougher against vibration and heat; ideal for plant rooms and rooftop units.
• Clear μF labelling → faster swaps and less guesswork when you’re racing the weather.

Why This Product Matters

Up on a roof in 40-degree heat, you want gear that just works. Swap a tired run cap with the right μF and you’ll usually see cleaner starts, quieter motors and happier clients — fair dinkum difference. This threaded M8 version gives you a neat, repeatable mount so you can fit once and move on. If you’re also replacing a start unit on the same system, grab a matching start capacitor while you’re there and she’ll be right. For broader choices, see the general run capacitor range.

Pro Tip

Always discharge and isolate before testing or swapping caps. If you’re chasing quick, on-site μF checks, a dedicated capacitor tester like the SUPCO MFD10 saves time and reduces misdiagnosis. Also, follow electrical safety guidance from Safe Work Australia.

Compatibility & System Info

• Suited to single-phase induction/PSC motors in HVAC fans, blowers and some compressors.
• Voltage: 450 VAC (use equal or higher voltage rating than OEM; never lower).
• Capacitance: 4–60 μF (match motor nameplate). Selection is motor-specific, not refrigerant-specific.
• Mount: Threaded M8 bolt (fixed).

Local jobsite note: From humid Brisbane plant rooms to salty Sydney coastal installs, the aluminium case and threaded mount handle vibration and exposure like a champ — bloody good for fit-and-forget service runs.

FAQs

How do I pick the right μF?
Match the μF on the motor nameplate or the OEM capacitor. If you need other formats (non-threaded, different case), check the full run capacitor range.

How do I test a run capacitor quickly?
Use a meter with capacitance or a dedicated tester. This how-to explainer covers the basics: How to test a motor capacitor.

Do I also need a start capacitor?
Many compressors use both. If the system has a separate start cap, replace like-for-like: Motor Start Capacitors.
