## Description

A capacitor is an electric component that temporarily stores an electrical charge. A "run capacitor" is used to boost the starting torque and efficiency on electric motors or compressor.Round capacitors come in a variety of sizes, depending on the capacitance (µF = MFD = micro farad), such as 50 µF, and also the voltage. A 440 volt capacitor can be used in place of a 370 volt, as it is build better, but the 370 can’t be used in place of a 440 volt. It will work for a while and will fail prematurely, as exceeding the capacitor's rated voltage will cause the dielectric to break down and the capacitor to short out. It is like a Ferrari that can do 440 miles per hour, driving on a road that have speed limit of 370 m/h. The capacitance(µF or MFD or micro farad) must be the same or stay within 10%+ or 5%- of its original value . Example: 50 µF cap can be substituted by 48 - 55 MFD with the same or better voltage ratings capacitor.If your motor or fan is not able to start, or the capacitor is bulged on top most likely your capacitor is defective. Round capacitor can be used to substitute oval shape one with the same MFD AND Volt specs.You will ask “Why I need a Cap that is rated 440V in my A/C?”Answer: You need to realize that a motor is an inductive device. When the supply voltage is applied to the motor run winding, the voltage across the start winding will be increased to a higher voltage value. A motor acts like a transformer with the run winding acting as the primary and the start winding acting as the secondary. This is why the capacitor has a much higher voltage rating than the 230 being the supply voltage.If a Capacitor is not EIA-456-A approved means it is NOT approved for USA market.

## Questions & Answers

**Q: i have a shallow well pump moter with a bad run  capacitor cbb60  40uf 450v heigh 3 5/8"  dia. 1 3/4" what is a suitable replacement**
A: You should search for a 40uF Cap with the proper Voltage rating.  If your Pump is connected to 240VAC then you will need the high Voltage rating.  https://www.amazon.com/BOJACK-Circular-Capacitor-Condenser-Straight/dp/B07SBQNQ6S/ref=sr_1_2_sspa?crid=2476N4H01OOPA&dchild=1&keywords=starting+capacitor+40uf&qid=1627736215&sprefix=40uF+Starting+%2Caps%2C182&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUE1OVpMWEhPU0IyVUwmZW5jcnlwdGVkSWQ9QTA3NDQxMjYyTlVNSTFCNDdHOFA3JmVuY3J5cHRlZEFkSWQ9QTA3NDc1MzIyNzFBS1pLMVNRRlk0JndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==

**Q: can i get the dimensions of the capacitor?**
A: It's approximately 3.5. To 4 inches long 2inch diameter

**Q: I have a delta ap400 dust collector with blown capacitor 50uf +/-5% 250v. will this work?**
A: Yes,it will work.Just make sure you have enough space to install it.

**Q: I have  to replace the 50uF capacitor in my 9500 watt generator,  Will this work ??**
A: If your old capacitor is rated 120v or 240v or 370 or 440VAC , yes this will work.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Solved My Breaker Tripping Issue!
*by C***Y on May 15, 2025*

Works great! My air compressor tripped my circuit breaker whenever I tried to turn it on. Turns out it was a bad starter capacitor inside the air compressor. No issues since I replaced it and it's been running strong.Pictures are from the old cap I replaced. This cap was an exact match.

### ⭐⭐⭐⭐⭐ Runs Great
*by C***Y on June 8, 2025*

Awesome & corrected the issue. Running great since 2019!

### ⭐⭐⭐⭐⭐ Worked for me.
*by C***P on June 1, 2025*

Bought this for my pool pump. Saved me 200 for a new pump.
