Rectorseal usa2233 Dual Run Capacitor 45/7.5 Mfd 370/440V

Product Description

The RECTORSEAL usa2233 is a round dual run capacitor rated at 45/7.5 microfarads (MFD) and designed to operate at 370 or 440 volts. Dual run capacitors serve two motor windings simultaneously — typically the compressor and the condenser fan motor — within a single canister. This design reduces the number of components in the electrical panel and simplifies replacement. The usa2233 is intended for installation by licensed HVAC technicians servicing residential and light commercial air conditioning and heat pump equipment.

This capacitor is suited for split-system air conditioners and heat pumps where the existing dual run capacitor has failed or shows signs of bulging, leaking, or reduced capacitance. The 370/440-volt dual-rating makes it compatible with systems wired to either voltage standard, which is common across a broad range of condensing unit vintages. Technicians replacing a failed start-assist or run capacitor during a seasonal tune-up or no-cool service call will find this a direct form-factor match for round-style capacitor brackets.

Key Features

• Dual run capacitor supports two motor loads — compressor and condenser fan — in one round canister
• 45/7.5 MFD dual capacitance rating covers both motor windings
• 370/440-volt dual-voltage rating suits a wide range of residential and light commercial condensing units
• Round canister form factor fits standard round capacitor mounting brackets and straps

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial air conditioning or heat pump condensing units requiring a round 45/7.5 MFD 370/440-volt capacitor.

Installation Notes

Dual run capacitors must be replaced by a licensed HVAC technician. Disconnect and lock out all power to the condensing unit before removing the access panel and discharging the existing capacitor using an insulated resistor or discharge tool — never short the terminals directly. Verify the MFD and voltage ratings on the nameplate match before installing the replacement, and ensure all terminal connections are secure and properly insulated after installation.
