## Overview

The VEXUNGA 20uF CBB65 run start capacitor is a robust, precision-engineered component designed for one-way AC motor start and run applications. Featuring a durable aluminum case and metallized polypropylene dielectric, it operates reliably across a wide temperature range (-40℃ to +70℃) and supports voltages up to 450VAC. Its direct replacement design fits a broad range of 250-450V capacitors, making it an essential upgrade for air conditioners, pool pumps, and single-phase motors. With a 60,000-hour lifespan and high safety rating, it ensures long-term, stable performance and helps prevent costly motor failures.

## Description

Product Description VEXUNGA Start and operate air conditioning condenser This capacitor is used for start-up and operation of one-way motors, such as Motor Run or Heat Pump Air Conditioner or Condenser Straight Cool.It is small in size, lightweight, heat resisting and anti-explosion. This kind of capacitor uses polypropylene film (thickened by zinc and aluminum ) as medium, coiling by Automatic winding machine, Packaged plastic shell, filling epoxy, Made Capacitors with good sealing, insulation performance, self-healing, low loss, low inherent temperature rise, stable performance, good reliability and longer life. The air conditioning condenser is small, lightweight, heat resistant and explosion proof. Capacitors are available in different sizes, but depending on the capacitance (µF or MFD) and the voltage. VEXUNGA starting capacitor is a good choice!!! SPECIFICATIONS Model: CBB65 （Universal model). Case Material: unpainted aluminum case. Dielectric Material: metallized polypropylene film. Available Capacitance: 20uf . Capacitance Tolerance:±5%. Operating temperature: -40℃ to +70℃/-104℉ to +158℉ . Frequency: 50/60 Hz . Operating Life:60,000 hours with 94% survival. Dissipation Factor: 0.1% maximum . Applicable to the frequency of 50hz / 60hz ac power supply one-way moto r starting and running, and it is widely used for pool pump, washing machine, cleaning machine, single phase electric motor, air compressor as starting and running. "WHEN" does the AC capacitor need to be replaced? - The fan of the air conditioning did not turn - it no longer worked . - The air conditioning was buzzing , but there was no air flow. - The AC fan rotated temporarily and the external pump did not start . The air conditioning has stopped cooling – the compressor in the condenser may not turn on. As the capacitor gets older , the motor may become louder and seem to run slower . You can extend the life of your engine by replacing it before it weakens. Over time, the capacitor becomes too weak to start the motor, and if the motor does not start, a short circuit may occur. Timely replacement of the capacitors is crucial for air conditioning maintenance. "VERY EASY" to replace the AC capacitor Turn off the air conditioning first. Second, remove the AC capacitor. Finally, make sure you know which cable is suitable for which connection – direct replacement without changing cables or adapters – and confirm the corresponding capacitance (µF or MFD) and voltage. What is important: replace the air conditioner itself, which will save you a lot of money and time . The package includes 1 piece x VEXUNGA 20uF 20 MFD 370/440/450 VAC starting and operating round AC capacitor.

Review: It does exactly what it needs to do - I was quoted £200 to repair my hot tub. But after a quick Google I found this range of capacitors were the direct replacement although the old one was a rounded rectangle and these are cylinders. These dont come with a cap to cover the connectors so I had to make out of a spray can lid.
Review: Generic replacement for branded powertool - Perfect replacement for a failed capacitor in my 35 year old DeWalt Powershop radial arm saw.

Perfect replacement for a failed capacitor in my 35 year old DeWalt Powershop radial arm saw.

### ⭐⭐⭐⭐⭐ Works perfectly
*by M***D on 24 January 2025*

My twenty year old garden shredder stopped working. Using the Internet I diagnosed the problem as a faulty capacitor. A web search turned up no direct replacement as the age of the shredder meant spares were unavailable. Matching the model type, voltage, uF value etc. on Amazon I came across this one. Purchased, it arrived next day, fitted in 10 minutes and the shredder is now running better than it has in a long time. Very pleased, and a lot cheaper than a new garden shredder!
