With a long 60,000-hour lifespan and easy plug-and-play installation, it’s the smart, reliable choice to keep your cooling systems running efficiently and quietly. ## 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: 45uf . 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 45uF 45 MFD 370/440/450 VAC starting and operating round AC capacitor. Review: Good for AC start capacitor - Got my AC back up and running! Less than 10 minute install with no assembly required. Good quality. Review: Prodotto ottimo - Perfetto per il motore della circolare da banco. ## Features - VEXUNGA 45uF ±6% 370/440/450 VAC CBB65 round run start capacitor replacement for ALL 250 & 300 & 370 & 440 & 450 Volt capacitors. - 45 MFD Capacitor size measures ( 1.97inch / 50mm ) in Diameter x ( 3.94inch / 100mm ) in Height. - Operating temperature: -40℃ to +70℃/-104℉ to +158℉.
