The RECTORSEAL usa2240 is a round dual run capacitor rated at 55/5 microfarads (MFD) and compatible with both 370-volt and 440-volt systems. Dual run capacitors serve two motor windings simultaneously, supplying the phase-shifted current needed to start and run the compressor and condenser fan motor within a single unit. This round-style capacitor is a standard format used across residential and light commercial HVAC equipment. Licensed HVAC technicians handle replacement during routine maintenance calls or when a failed capacitor causes hard-start or no-start conditions in cooling equipment.
The usa2240 is suited for split-system air conditioners and heat pumps where the original equipment specifies a round dual run capacitor at 55/5 MFD. Its dual-voltage rating of 370/440 volts accommodates the range of supply voltages found in residential and light commercial installations. Technicians typically encounter this capacitor type in the outdoor condensing unit, mounted inside the control compartment near the contactor. When original equipment capacitance has drifted beyond acceptable tolerance, replacement with a correctly rated unit restores normal motor operation.
Designed as an OEM-style replacement dual run capacitor for residential and light commercial air conditioning and heat pump condensing units requiring a round 55/5 MFD 370/440-volt capacitor.
Capacitor replacement is performed by licensed HVAC technicians. Disconnect and lock out power to the condensing unit at the disconnect box before opening the control compartment. Capacitors can retain a dangerous charge even after power is removed — discharge the capacitor safely using an approved resistive discharge tool before handling. Verify that the replacement capacitor matches the original MFD ratings and voltage rating before installation, as mismatched capacitance values can damage motor windings.
