Rectorseal M11148 Motor Start Capacitor 124-156 Mfd 250/220V

Product Description

The RECTORSEAL M11148 is a round motor start capacitor rated at 124-156 microfarads (MFD) and 250/220 volts, designed to provide the starting torque boost required by single-phase compressors, condenser fan motors, and refrigeration equipment. Built with a phenolic composition, the M11148 handles a wide temperature range from -40 degrees F to 149 degrees F (equivalent to -40 to 65 degrees C), making it suitable for both cold-weather and high-ambient installations. HVAC and refrigeration technicians install this capacitor as a replacement component in equipment experiencing hard-start conditions or failed start capacitor failures.

The M11148 is recommended for use in residential and commercial air conditioning systems and refrigeration equipment where a motor start capacitor is required. Its 50/60 Hz compatibility makes it appropriate for both standard North American and international-frequency applications. With a maximum of 20 starts per hour, it suits typical cycling demands found in AC condensing units and refrigeration compressor circuits. The two-terminal, round form factor fits common capacitor mounting arrangements found in condenser cabinets and refrigeration equipment enclosures.

Key Features

• 124-156 MFD range allows coverage across multiple motor starting requirements
• Rated for 250/220 volts to suit common single-phase motor start circuits
• Phenolic composition for durability in demanding HVAC and refrigeration environments
• Wide operating temperature range: -40 to 65 degrees C
• 50/60 Hz rated for broad application compatibility
• Supports up to 20 starts per hour for typical cycling equipment

Compatibility

Recommended for use in residential and commercial AC and refrigeration equipment requiring a round, two-terminal motor start capacitor rated at 124-156 MFD and 250/220 volts.

Installation Notes

Motor start capacitors are installed by licensed HVAC or refrigeration technicians. Always disconnect and lock out power to the unit before handling any capacitor, and discharge the existing capacitor fully before removal, as start capacitors can retain a charge after power is removed. Verify that the replacement MFD rating and voltage rating meet or exceed the original equipment manufacturer specifications before installation. Follow all applicable NEC guidelines for low-voltage motor circuit components.
