BOJACK Dual Run Capacitor 55+5µF 370/440V CBB65 Round — 3-Terminal, Metallized Polypropylene

BOJACK 55+5µF CBB65 dual run circular start capacitor is a compact, metal-shelled unit that combines two capacitors into one module to run a compressor and a fan motor in HVAC and similar AC motor systems.

This BOJACK CBB65 dual capacitor is designed for 50/60Hz AC motors and pairs a 55µF and a 5µF section in a single round housing. Built from metallized polypropylene film with a metal shell, it offers a wide operating temperature range and a high safety interrupt rating, making it suitable for central air conditioners, heat pumps, condensers, and other motor-start or motor-run applications where space is limited and reliable electrical performance matters.

How does this dual run capacitor simplify HVAC repairs?

By merging two capacitances into one packaged unit, the BOJACK dual run capacitor reduces wiring complexity and the number of components technicians need to replace. Its three labeled terminals (Herm/H, Fan/F, and C) map directly to compressor, fan and common connections for straightforward installation.

• 55+5µF combined values in one enclosure
• Three labeled top terminals for Herm, Fan and Common
• Round CBB65 form factor fits many replacement needs
• Direct swap for many OEM part numbers listed in the features

What electrical and physical specs should I check before swapping this capacitor?

Match the microfarad (µF) ratings and verify the voltage rating of the replacement matches or exceeds the original. The BOJACK unit is rated 55+5µF ±6% at 370V/440V AC and can be used at either 370V or 440V systems when a higher-voltage option is acceptable.

• Capacitance: 55+5µF with ±6% tolerance
• Voltage: 370V/440V AC rated
• Frequency: 50Hz/60Hz compatible
• Size: Diameter 2.56" x Height 4.14" for fit checks

Is this capacitor durable and safe for outdoor condenser use?

The BOJACK CBB65 uses metallized polypropylene film and a metal shell to resist heat and mechanical stress, and it carries a high interrupt rating for safer operation under fault conditions. Its operating temperature range covers -40°C to +70°C (-104°F to +158°F), making it suitable for many outdoor condenser and compressor environments.

• Operating range: -40°C to +70°C (-104°F to +158°F)
• Safety rated interrupt: 10,000 AFC
• Heat-resistant metallized polypropylene dielectric
• Metal shell for mechanical protection and grounding

Can this round capacitor replace oval or different-voltage models?

Round BOJACK CBB65 units can substitute oval or other shapes provided the µF and voltage specifications match. A 440V-rated capacitor can typically replace a 370V part for added margin, but you should not replace a 440V unit with a lower-voltage 370V model.

• Shape substitution allowed if µF and V ratings match
• 440V unit can replace 370V for higher voltage tolerance
• Do not use a 370V unit where 440V is required
• Confirm terminal labeling matches your system wiring

Who is this for: HVAC technicians, maintenance teams, and DIY-savvy homeowners who need a compact, dual-capacitance replacement for central air conditioners, heat pumps, condensers, or compressor/fan motor combos. Choose the BOJACK 55+5µF CBB65 when you require a durable, easily wired dual run capacitor with broad temperature tolerance and a high safety interrupt rating.
