45+5 uF 45/5 MFD ±5% 370/440VAC CBB65 Dual Run Round Capacitor - CE cRUus Certified

45+5 uF 45/5 MFD ±5% 370/440VAC CBB65 Dual Run Round Capacitor

Key Features

• Dual run configuration designed for simultaneous compressor motor and fan motor operation.
• Voltage rating: 370VAC / 440VAC (compatible with both).
• Capacitance tolerance: ±5%.
• Operating frequency: 50/60 Hz.
• Temperature range: -40°C to +70°C (-40°F to +158°F).
• Construction: CBB65 round metallic casing with standard terminal connections.
• Safety: CE and cRUus certified.

Replaces / Cross-Reference Part Numbers

• Replaces all 45/5 MFD/uF 370VAC and 440VAC dual run capacitors.
• Compatible with common industry part numbers including 97F9895 and other CBB65 specification units with matching capacitance values.
• Universal replacement for OEM capacitors of the same ratings.

Compatibility & Fitment

• Suitable for HVAC systems, central air conditioners, heat pumps, and outdoor condenser units.
• Fits motor run and fan start applications.
• Verify physical dimensions to ensure clearance within your specific control box housing.

When to Replace

• Visual signs of failure: Bulging top, leaking oil, or scorched terminals.
• System failure: The outdoor condenser fan fails to spin or the compressor hums but does not start.
• Performance decline: Air conditioner struggles to cool or fails to maintain set temperatures.
• Measured value: When a multimeter indicates the capacitance has drifted outside of the specified ±5% tolerance.

Installation Tips

• Ensure all power to the HVAC system is disconnected at the circuit breaker before beginning work.
• Discharge the old capacitor using an insulated screwdriver across the terminals before handling.
• Take a photo of the existing wire connections to ensure proper placement on the new unit (Common, Herm, and Fan terminals).
• Ensure terminals are seated securely and connections are tight to prevent arcing.
• Do not overtighten mounting hardware.
