Maintain peak cooling efficiency with the CBB65 25uF 450V Air Cond Running Capacitor. Specifically designed for high-demand HVAC applications, the CBB65 series features a rugged, oil-filled aluminum housing that provides superior durability compared to standard plastic motor capacitors. This unit provides the continuous electrical phase shift required for your air conditioner's compressor and fan motors to start reliably and run with optimal energy efficiency.
High-Output 25uF Capacity: Rated at 25uF ±5%, providing stable capacitance for high-torque compressors and large condenser fans.
Explosion-Proof Aluminum Shell: Equipped with a "Protected 10,000AFC" internal safety mechanism designed to disconnect the capacitor in the event of an electrical fault, preventing case rupture.
Enhanced Heat Dissipation: The metallic oil-filled construction allows for rapid heat transfer, essential for capacitors housed in hot outdoor condenser units.
450V AC Heavy-Duty Rating: Engineered for 450VAC operation, ensuring a robust safety ceiling against power surges and voltage fluctuations in 50/60Hz systems.
Industrial Safety Certified: Fully compliant with CQC and CE standards, featuring a climatic category rating of 40/70/21 for reliability in extreme weather.
Air Conditioner Compressors: Primary start and run support for residential and light commercial AC units.
HVAC Condenser Motors: Supports the outdoor fan for consistent heat exchange performance.
Refrigeration Systems: Ideal for large-scale walk-in coolers and commercial refrigeration compressors.
Heat Pumps: Provides reliable, year-round performance in both heating and cooling cycles.
Model: CBB65A.
Capacitance: 25uF ±5%.
Rated Voltage: 450V AC.
Frequency: 50/60Hz.
Can I use a CBB65 to replace a CBB60 capacitor?
While both are run capacitors, the CBB65 (Aluminum) is the standard for HVAC because its metal shell dissipates heat better and includes specific explosion-proof safety features not always found in the plastic CBB60 models.
What does the "±5%" mean for my motor?
This is the tolerance rating. A 25uF capacitor is considered healthy if its actual measured value is between 23.75uF and 26.25uF. If it tests below this range, your motor will run hot and inefficiently.
How do I know if my capacitor is "blown"?
Look for a "domed" or "bulged" top on the aluminum case. If the top is no longer flat, the internal safety protector has likely tripped, and the unit must be replaced immediately to prevent compressor damage.
