Rectorseal M12292 Dual Run Capacitor 55/5 Mfd 440V

Product Description

The RECTORSEAL M12292 is a dual run capacitor rated at 55 plus 5 microfarads (MFD) and 440 volts, designed to support the simultaneous operation of a compressor and condenser fan motor in a single package. This round capacitor provides the starting and running capacitance required to maintain motor efficiency and stable operation in air conditioning and heat pump systems. Licensed HVAC technicians install this component as a direct replacement when a failed capacitor causes hard starting, motor humming, or system shutdown. Its compact round housing measures 2.5 inches in diameter and 4.375 inches in height.

This capacitor is suited for residential and light commercial HVAC applications where a single dual-rated capacitor serves both the compressor and the condenser fan motor. It is a common service replacement in split-system air conditioners and heat pump condensing units. The 440-volt rating provides a conservative operating margin in standard 240-volt systems, which helps extend service life under high-ambient conditions. HVAC service technicians typically stock dual run capacitors of this rating for seasonal tune-up and emergency service calls.

Key Features

• Dual capacitance rating of 55 plus 5 MFD supports compressor and condenser fan motor from a single unit
• 440-volt rating provides operating margin above standard 240-volt system requirements
• Round housing for compatibility with common capacitor mounting brackets and clips
• Compact footprint at 2.5 inches diameter and 4.375 inches height fits standard condensing unit cabinets

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a 55 plus 5 MFD, 440-volt round capacitor.

Installation Notes

A licensed HVAC technician should perform capacitor replacement. Always disconnect and lock out power to the condensing unit at the disconnect box before opening the electrical compartment. Capacitors store a charge and must be safely discharged before handling, even after power is removed. Follow local codes and the unit manufacturer's wiring diagram when connecting the replacement capacitor.
