Optimize your HVAC system’s performance with the CBB65 35uF 450V Air Cond Running Capacitor. Engineered for the intense thermal demands of modern air conditioning units, the CBB65 series features a rugged, oil-filled aluminum housing that provides superior safety and durability compared to standard plastic alternatives. This unit provides the continuous electrical support needed for your compressor to start reliably and run with maximum energy efficiency, even during the hottest summer days.
Heavy-Duty 35uF Capacity: Rated at 35uF ±5%, providing the precise electrical energy storage required for high-torque AC compressors and larger condenser fan motors.
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.
Superior Heat Dissipation: The metallic, oil-filled construction allows for rapid heat transfer, which is essential for components housed in hot outdoor condenser units.
450V AC Industrial Rating: Built to handle standard 450VAC applications across 50/60Hz frequencies, ensuring a robust safety margin against domestic power surges.
Certified Safety Standards: Fully compliant with CQC and CE certifications, featuring a climatic category rating of 40/70/21 for reliability in extreme weather conditions.
Air Conditioner Compressors: Primary start and run support for medium-to-large residential AC units.
HVAC Condenser Motors: Supports outdoor fans for consistent heat exchange performance.
Commercial Refrigeration: Ideal for large-scale refrigeration compressors and cooling systems.
Heat Pumps: Provides reliable, year-round performance in both heating and cooling modes.
Model: CBB65A.
Capacitance: 35uF ±5%.
Rated Voltage: 450V AC.
Frequency: 50/60Hz.
Can I replace a 30uF or 40uF capacitor with this 35uF model?
It is strongly recommended to match the original rating exactly. While a motor might start with a different value, using the wrong capacitance (beyond the ±5% tolerance) can cause the compressor to run hot, draw excess power, and eventually fail.
What makes the CBB65 better than a plastic CBB60 for my AC?
The CBB65 (Aluminum) is the industrial standard for HVAC because its metal shell dissipates heat effectively in outdoor environments. It also includes an internal safety disconnect (AFC) that the plastic CBB60 models typically lack.
How do I know if my 35uF capacitor is bad?
Look for a "bulged" or rounded top on the aluminum case. If the top is not perfectly flat, the internal safety protector has likely tripped. Another sign is if the AC compressor "hums" but fails to kick on.
