Rectorseal usa2291 Dual Run Capacitor 35/7.5 Mfd 370/440V

Product Description

The RECTORSEAL usa2291 is a round dual run capacitor rated at 35/7.5 MFD and 370/440 volts, designed for use in residential and light commercial HVAC systems. Dual run capacitors serve two motor loads simultaneously, providing starting and running assistance to both the compressor and the condenser fan motor from a single component. This configuration reduces cabinet space requirements compared to two separate capacitors. Licensed HVAC technicians install this part during capacitor replacement service calls, seasonal maintenance, or when diagnosing motor starting failures.

This capacitor is suited for split-system air conditioners and heat pumps where the condensing unit requires a shared capacitor for the compressor and fan motor. The 370/440 volt dual-rated design allows installation across a wide range of single-phase condensing units operating on standard residential and light commercial supply voltages. It is a common replacement component in service situations where the original capacitor has failed due to heat exposure, age, or voltage stress.

Key Features

• Dual run capacitor supports both compressor and condenser fan motor from one unit
• 35/7.5 MFD dual capacitance rating covers standard compressor and fan motor requirements
• 370/440 volt dual-rated for broad voltage compatibility across single-phase systems
• Round form factor fits standard condensing unit capacitor brackets and clips

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioning and heat pump condensing units requiring a 35/7.5 MFD 370/440 volt round capacitor.

Installation Notes

Capacitor replacement is performed by licensed HVAC technicians. Always disconnect and lock out power to the condensing unit before servicing. Capacitors store a lethal electrical charge even after power is removed — discharge the capacitor using an insulated resistor tool before handling terminals. Follow NEC guidelines for low-voltage disconnect and equipment grounding when replacing run capacitors.
