Rectorseal M11027 Motor Start Capacitor 590-708 Mfd 110/125V

Product Description

The RECTORSEAL M11027 is a round motor start capacitor rated at 590-708 microfarads (MFD) and 110/125 volts, designed to provide the high-torque starting boost that single-phase compressor and fan motors require. Built with a phenolic composition and rated for 50/60 Hz operation, this capacitor delivers reliable short-duration current surge assistance during motor startup. The M11027 handles up to 20 starts per hour and is engineered to perform across a wide temperature range, from -40 degrees F to 149 degrees F (approximately -40 to 65 degrees C). HVAC technicians and refrigeration service techs are the primary installers of this component.

The M11027 is recommended for use in residential and commercial air conditioning systems and refrigeration equipment where motor start assistance is required. It is suited for applications where a round-body capacitor fits the existing mounting configuration. The wide MFD range of 590-708 MFD accommodates motor starting requirements across a variety of compressor and fan motor sizes found in typical AC and refrigeration service scenarios.

Key Features

• 590-708 MFD rating provides a wide range for motor start compatibility
• Rated for 110/125 volt operation at 50/60 Hz
• Phenolic composition construction for motor start duty

Compatibility

Recommended for use in residential and commercial AC and refrigeration equipment requiring a motor start capacitor rated at 590-708 MFD and 110/125 volts.

Installation Notes

Motor start capacitors must be installed by a qualified HVAC or refrigeration technician. Always disconnect and lock out power to the unit before handling any capacitor, as capacitors can retain a dangerous charge even after power is removed — discharge the capacitor safely before making contact. Verify that the replacement MFD range and voltage rating match or fall within the motor nameplate specifications before installation. Follow applicable local codes and manufacturer guidelines when servicing capacitor circuits.
