Maintain the peak efficiency of your most powerful cooling systems with the CBB65 80uF 450V Air Cond Running Capacitor. This industrial-grade unit is specifically designed for the massive electrical and thermal demands of high-tonnage (5-ton and larger) commercial and residential air conditioning units. Housed in a rugged, oil-filled aluminum casing, it offers significantly better heat dissipation and safety than plastic alternatives, ensuring your heavy-duty compressor starts reliably and maintains optimal energy efficiency even under extreme seasonal loads.
Ultra-High 80uF Capacity: Rated at 80uF ±5%, providing the massive electrical energy storage required for high-torque compressors and industrial blower motors.
Explosion-Proof Aluminum Design: Features an integrated "Protected 10,000AFC" safety mechanism that automatically disconnects the capacitor in the event of an electrical failure, preventing case rupture.
Superior Heat Management: The metallic, oil-filled shell dissipates heat rapidly, critical for components housed in hot outdoor condenser units exposed to high ambient temperatures.
450V AC Industrial Resilience: Built to handle standard 450VAC applications across 50/60Hz frequencies, offering a robust safety ceiling against power surges and voltage spikes.
Professional Safety Certifications: Fully compliant with CQC and CE standards, with a 40/70/21 climatic rating for year-round reliability in harsh environments.
High-Tonnage AC Compressors: Ideal for 5-ton+ residential and commercial air conditioning systems.
Heavy-Duty HVAC Motors: Supports larger outdoor fan motors and high-volume ventilation systems.
Commercial Refrigeration: Used in high-capacity refrigeration compressors for food storage and industrial cooling.
Heat Pump Systems: Provides stable starting and running torque in both heating and cooling operation modes.
Model: CBB65A.
Capacitance: 80uF ±5%.
Rated Voltage: 450V AC.
Frequency: 50/60Hz.
Can I replace a 70uF or 75uF capacitor with this 80uF model?
For run capacitors, you must stay within ±5% of the motor's specified rating. Using an 80uF unit to replace a 70uF unit will likely cause the motor to run hot and fail prematurely. Always match the manufacturer's microfarad (uF) specification exactly.
What is the advantage of the aluminum shell?
In high-power applications like 80uF, heat generation is significant. The aluminum shell dissipates this heat much better than plastic, and the integrated AFC protection is essential for safety in high-wattage systems.
How do I know if my 80uF capacitor is failing?
Look for a "bulged" or rounded top on the aluminum housing. If the lid is no longer flat, the internal safety protection has activated, and the part must be replaced immediately to prevent compressor damage.
