Rectorseal m12107 Run Capacitor 7.5 Mfd 440V Round

Product Description

The RECTORSEAL m12107 is a single-capacitance run capacitor rated at 7.5 microfarads (MFD) and 440/370 volts, designed for continuous-duty motor starting and run applications in air conditioning and refrigeration systems. Built with an aluminum composition and housed in a round enclosure, this capacitor maintains stable electrical performance across a wide temperature range of -40 degrees F to 158 degrees F (equivalent to -40 to 70 degrees C). With a rated operational life of 60,000 hours, it is engineered to hold up under the sustained electrical loads typical of compressor and fan motor circuits. HVAC technicians install this capacitor as part of routine seasonal maintenance or component replacement service calls.

This run capacitor is suited for residential and commercial air conditioning and refrigeration equipment. It functions in single-capacitance motor circuits where a dedicated run capacitor is required, separate from a dual-round or oval combination unit. The round form factor makes it a common fit for condenser units, air handlers, and refrigeration compressor decks where space and mounting orientation favor a cylindrical can design. Technicians working on light commercial and residential split systems or self-contained refrigeration units will find this capacitor applicable to a broad range of single-phase motor loads.

Key Features

• 7.5 MFD single capacitance rating for dedicated run-circuit applications
• Dual voltage rating of 440/370 volts supports common single-phase supply voltagesRound aluminum housing provides a compact, standard form factor
• Rated operational life of 60,000 hours for long-term continuous-duty use
• Wide temperature range: -40 to 70 degrees C (-40 to 158 degrees F)
• Compatible with 50 Hz and 60 Hz electrical systems
• Four-terminal configuration for flexible wiring connections

Compatibility

Designed for use in residential and commercial air conditioning and refrigeration systems requiring a single-capacitance, round run capacitor rated at 7.5 MFD and 440/370 volts.

Installation Notes

Run capacitors must be installed by a qualified HVAC technician. Always disconnect and lock out power to the unit before handling capacitors, and discharge the capacitor fully before removal, as stored charge can be present even after shutdown. Verify that the MFD rating and voltage rating of the replacement match or meet the specifications on the original equipment nameplate. Follow all applicable NEC requirements and local codes when servicing motor capacitor circuits.
