- Tolerance: ± 5%
- Voltage: Dual Rated 370 or 440 VAC
- Frequency: 50/60 Hz
- Operating Temperature: -40°C to +70°C (-40°F to 158°F)
- Construction: Round, oil-filled aluminum case

- Safety Standard: 10,000 AFC Protected
Replaces / Cross-Reference Part Numbers
- This capacitor replaces any round 30/5 uF 370V or 440V dual run capacitor. While this is not an exhaustive list, it is a direct replacement for part numbers including: 97F9833, C3305R, C4305R, P291-3054R, TRCFD305, USA2227, and CBB65.
Compatibility & Fitment
- Used in air conditioning units, heat pumps, condensers, and other HVAC systems to start and run a compressor motor (30 uF) and a fan motor (5 uF) simultaneously.
- To ensure compatibility, match the specifications of your original capacitor:
- Capacitance: Must be 30+5 uF/MFD.
- Voltage: Must be 370V or 440V. This 440V capacitor can safely replace a 370V capacitor.
- Shape & Size: Must be a round capacitor with similar dimensions to fit the mounting bracket.
When to Replace
- Your outdoor unit hums but the fan does not spin or the compressor will not start.
- The fan or compressor motor starts slowly or not at all.
- The original capacitor shows physical damage, such as a bulging top, swelling, or fluid leaks.
Installation Tips
- Disconnect all electrical power to the HVAC unit before handling.
- Safely discharge the existing capacitor by shorting across the terminals with an insulated screwdriver.
- Take a picture or note the wire placement on the C, FAN, and HERM terminals before disconnecting.
- Connect the new capacitor by matching the wires to the corresponding terminals.

Fun to fetch
Size: 5 Inch, Color: Red, Size: 5 Inch, Color: Red
Perfect size for my 1 yr old Cavapoo that is ball obsessed. This ball is fun to toss around in the yard to exercise and wear out my energetic boy. Perfect for after my work day when I don’t have the energy to match his energy level. He gets to run and chase and I can enjoy his playtime too. Overall the ball is durable and I have confidence it will last for a very long time. We have 2 sizes, small and medium, for my 30 pound athletic pup. He enjoys both equally.

Dog loves them
Size: 6 Inch, Color: Independence Day
My dog loved the first ball I got her, so I got her a second one. Both hhavr been very durable (she likes to puncture things with her teeth). I left each ball slightly deflated, so they were still firm, but she could bite them without issues. She has not punctured either ball yet. I did have to watch her because she started trying to chew the tabs off because she was bored. She has not chewed one off, just started thinking about it, and did a tiny bit of damage to one tab.
She loves these balls. We have played tug of wat with them too, so yhe tabs are sturdy, and so is the ball.
The dog did not care what collar she got, so I grabbed the least expensive one, and the 6 inch. She is a medium sized dog with razor teeth, and these work great.

Not recommended for the aggressive player..
Size: 6 Inch, Color: Red, Size: 6 Inch, Color: Red
First this ball was not delivered when it should have been. Second, the tabs are poorly made. One day of my dog playing with it and the tabs are already torn up. The ball itself is fun for her and has not deflated for now at least.

Best Balls Ever!!!
Size: Medium
These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!

Finally a ball my power chewers cannot destroy
Size: Medium
I have two dogs, an American Bully and an American Pit Bull Terrier, and both of them love to chew. Most balls last a very short time around here before they are shredded or missing big chunks. This one has actually held up. They chase it, tug on it and sit and chew on it, and it is still in one piece with no pieces breaking off.
One of my favorite things is being able to put food inside. I add some kibble or small snacks, and they will happily sit and work on it for a long time. It keeps them busy, gives them something safe to chew, and they get a little reward while they play. When they are done, I just rinse it out and it is ready to go again.
If you have strong jawed dogs that usually destroy toys, this ball is worth trying. Mine really enjoy it and I feel better knowing they finally have a ball that can keep up with them.
