1 Pcs CBB65 Capacitor, 50uF 450V Run Round Capacitor for AC Motor and HVAC Compressor, Generator Air Conditioner Start

[Capacitance Value] Choose between 15uF and 50uF capacitance values according to your specific AC motor or compressor requirements. The 15uF version is suitable for smaller HVAC fans, air conditioner condensers, and light‑duty generators, while the 50uF model is intended for larger compressor units, heat pumps, and heavy‑duty motors. [High Voltage Rating] The CBB65 capacitor is rated at 450V AC, providing ample voltage margin over standard residential and commercial HVAC systems. The higher voltage rating reduces stress on the dielectric film, extends service life, and prevents catastrophic failure during voltage spikes or brownout conditions. [Metal Housing] Encased in a durable cylindrical aluminum shell that withstands high temperature, vibration, and moisture over time. The sealed metal housing keeps dust and moisture out of the internal components, while a top‑mounted pressure relief vent provides overpressure venting in the rare event of internal failure. [Extended Life] The internal dielectric uses a self‑healing metallized polypropylene film rated for 10,000 operating hours at rated temperature (typically 70°C). When a minor electrical breakdown occurs due to voltage transients, the metallized layer around the fault point vaporizes, instantly restoring insulation without catastrophic failure. [Wide Compatibility] The CBB65 capacitor is a common replacement part for single‑phase AC motors in air conditioners, heat pumps, condensing units, air handlers, and standby generators. It acts as a run capacitor, remaining permanently in the circuit to improve power factor and motor efficiency.
