Maintain peak cooling efficiency for your most powerful HVAC units with the CBB65 60uF 450V Air Cond Running Capacitor. This industrial-grade unit is specifically engineered for high-tonnage (5-ton+) residential and commercial air conditioning systems. Encased in a rugged, oil-filled aluminum housing, it provides superior heat dissipation and safety compared to standard plastic alternatives, ensuring your compressor starts smoothly and maintains optimal torque during intense heat cycles.
Ultra-High 60uF Capacity: Rated at 60uF ±5%, providing the massive electrical phase shift required for high-torque compressors and heavy-duty industrial blower motors.
Explosion-Proof Aluminum Shell: Equipped with a "Protected 10,000AFC" internal safety mechanism that disconnects the capacitor in the event of an electrical fault, preventing the case from rupturing.
Superior Thermal Management: The metallic, oil-filled construction allows for rapid heat dissipation, essential for components housed in hot outdoor condenser units exposed to direct sunlight.
450V AC Heavy-Duty Rating: Built to handle standard 450VAC applications across 50/60Hz frequencies, offering a robust safety ceiling against power surges and voltage spikes.
Certified Industrial Safety: Fully compliant with CQC and CE certifications, with a climatic category rating of 40/70/21 for reliability in extreme weather conditions.
High-Tonnage AC Compressors: Primary start and run support for 5-ton+ residential and commercial AC units.
Industrial HVAC Motors: Supports larger outdoor fans and high-volume ventilation systems.
Commercial Refrigeration: Ideal for large-scale refrigeration compressors used in walk-in freezers and cold storage.
Heavy-Duty Heat Pumps: Provides reliable, year-round performance in both high-load heating and cooling modes.
Model: CBB65A.
Capacitance: 60uF ±5%.
Rated Voltage: 450V AC.
Frequency: 50/60Hz.
Can I use a 60uF capacitor if my old one was 55uF or 65uF?
It is critical to match the original rating exactly for run capacitors. Using a value outside the ±5% tolerance can cause the compressor motor to draw excessive current, run hot, and shorten its lifespan significantly.
Is this aluminum case better than the plastic ones?
For HVAC applications, yes. The CBB65 (Aluminum) dissipates heat faster and includes specialized internal safety disconnects (AFC) that standard plastic CBB60 units do not always have.
How do I know if my 60uF capacitor is dead?
Beyond a compressor that "hums" but won't start, look for a "bulged" or domed lid on the aluminum housing. If the top is no longer flat, the internal safety protector has tripped and the unit must be replaced.
