Description

70+5 uF MFD ±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.
