30 uF/MFD ± 5% 370 or 440 VAC Motor Run Round Capacitor
Key Features
- Capacitance Rating: 30 Microfarad (uF/MFD)
- Tolerance: ± 5%
- Voltage: Dual voltage rated for 370 VAC or 440 VAC applications
- Frequency: 50/60 Hz
- Case: Round aluminum case with steel cover
- Terminals: 1/4 inch male quick-connect terminals
- Safety: Pressure-sensitive interrupter mechanism
- Operating Temperature: -40° C to 70° C
Replaces / Cross-Reference Part Numbers
- This capacitor replaces any round, single-capacitance 30 uF capacitor with a voltage rating of either 370V or 440V.
- Always match the microfarad (uF/MFD) rating.
- The replacement capacitor's voltage rating must be equal to or greater than the original capacitor.
Compatibility & Fitment
- Commonly used for HVAC systems, air conditioner compressors, heat pumps, fan motors, and other electric motor applications.
- The round shape and standard terminal configuration allow for wide compatibility with units from multiple manufacturers.
- Verify physical dimensions (diameter and height) to ensure a proper fit within the existing mounting bracket and space.
When to Replace
- The motor hums but fails to start or struggles to start.
- The fan or compressor runs intermittently or at a reduced speed.
- The top of the existing capacitor is swollen or bulging.
- Fluid is leaking from the capacitor casing.
- A multimeter test shows the capacitance is outside the specified tolerance range.
Installation Tips
- Disconnect all electrical power to the equipment before beginning work.
- Safely discharge the old capacitor by shorting the terminals with an insulated-handle screwdriver.
- Note the wire placement on the old capacitor terminals before disconnecting. Taking a picture is recommended.
- Connect the wires to the corresponding terminals on the new capacitor.
- Secure the new capacitor with the original mounting strap or bracket.

Great in wall wire, easy to install
Size: 14/2 AWG-200 FT, Color: White
Ran this through studs for an in-wall 5.2 system, worked great, very easy to fish, wire threaded nicely, good copper, good connections. Easy to bend for 14 AWG.

Parts actually fit 11S.
Size: 23 Pack
Bought replacement parts from another vendor, but the brushes are nylon and do not last. Filters did not fit 11S, so I had to throw them away. Parts from this current kit fit perfect, brushes are rubber and seem more sturdy. Have not had to change them yet, but there were 10 replacement brushes in the kit, as the other kit only provided 4. Changed the filter also, picks up a lot more dust and dirt.
