70+5 uF ±5% 70/5 MFD 370/440 VAC Dual Run Start Round Capacitor

Key Features

  • Capacitance Rating: 70 + 5 Microfarad (MFD/uF)
  • Capacitance Tolerance: ±5%
  • Voltage Rating: 370 / 440 Volts AC (VAC)
  • Frequency: 50 / 60 Hertz (Hz)
  • Configuration: Dual run capacitor in a single round case
  • Terminals: Three terminals labeled for Common, Fan, and Compressor connections
  • Construction: Aluminum case, oil-filled, non-PCB dielectric
  • Safety: Integrated 10,000 AFC pressure-sensitive interrupter
  • Operating Temperature: -40 °C to +70 °C (-104 °F to +158 °F)
  • Standard: Tested to EIA-456-A specifications

Replaces / Cross-Reference Part Numbers

  • Replaces any round or oval dual run capacitor with matching 70/5 MFD and 370V or 440V specifications. A 440V capacitor can be used to replace a 370V capacitor.
  • Common part number formats include: CBB65, P291-7054R, USA2236, C3705R, C4705R, TRCD705, and CAP05070.
  • Compatible replacement for capacitors from brands such as Genteq, Packard, Titan, and TEMCo.

Compatibility & Fitment

  • Used in air conditioning units, heat pumps, condensing units, and other HVAC systems to run a compressor motor and a fan motor simultaneously.
  • Physical dimensions must be verified for fitment in the existing mounting bracket.
    • Diameter: Approx. 2.36 in (60 mm)
    • Case Height: Approx. 5.4 in (137 mm)
  • The dual voltage rating allows for use in both 370 VAC and 440 VAC applications.

When to Replace

  • Compressor or fan motor hums but fails to start.
  • AC unit requires a manual "push start" to get the fan spinning.
  • Air conditioner blows warm air.
  • Visible damage to the capacitor, such as a bulging top, swelling, or fluid leakage.
  • Capacitance measurement is outside the rated ¬±5% tolerance when tested with a multimeter.

Installation Tips

  • WARNING: Disconnect all electrical power to the HVAC unit before handling or replacing the capacitor.
  • Safely discharge the existing capacitor by carefully shorting across the terminals with an insulated screwdriver.
  • Before disconnecting, note the wire colors and their corresponding terminals ("C", "HERM", "FAN").
  • Connect the run wire from the compressor to the "HERM" terminal.
  • Connect the run wire from the fan motor to the "FAN" terminal.
  • Connect the common wire from the contactor to the "C" terminal.
  • Ensure all connections are secure before restoring power.

I think is a quality wire and affordable
Size: 2AWG 15FT + 15FT, Color: Red + Black
The wire is excellent; its thickness feels appropriate, and it appears to be high quality. I've installed it on my PV array, which delivers over 40 amps DC, and the wire handles this load well. MC4 connectors are not included but are pre-cut for easy installation, and I encountered no problems.
