Rectorseal M11010 Motor Start Capacitor 108-130 Mfd 110/125V

Product Description

The RECTORSEAL M11010 is a round motor start capacitor rated at 108-130 microfarads (MFD) and 110/125 volts, designed for single-phase induction motors in air conditioning and refrigeration equipment. Start capacitors provide a brief high-torque boost during motor startup, then drop out of the circuit once the motor reaches operating speed. The M11010 uses a phenolic composition and is rated for operation from -40 degrees F to 149 degrees F, making it suitable for a wide range of installation environments. With a rated frequency of 50/60 Hz, it is compatible with both standard North American and international supply frequencies.

This capacitor is recommended for use in residential and commercial AC and refrigeration applications. It is typically installed in compressor and condenser fan motor circuits where a start capacitor is required to bring the motor up to speed under load. HVAC technicians and refrigeration service professionals replace start capacitors as part of routine motor circuit diagnostics when motors fail to start, hum on startup, or trip on thermal overload. The M11010 supports up to 60 starts per hour, which suits the duty cycles of typical air conditioning and refrigeration compressors.

Key Features

• 108-130 MFD capacitance range accommodates tolerance variation in motor start circuits
• Rated for 110/125 volts and 50/60 Hz for broad application compatibility
• Phenolic composition construction for durability in HVAC and refrigeration environments
• Round shape for straightforward mounting in standard capacitor brackets and housings
• Operating temperature range from -40 degrees F to 149 degrees F
• Supports up to 60 starts per hour to match compressor and fan motor duty cycles

Compatibility

Designed as an OEM-style replacement motor start capacitor for residential and commercial air conditioning and refrigeration equipment requiring a 108-130 MFD, 110/125-volt round start capacitor.

Installation Notes

Motor start capacitors are typically installed or replaced by licensed HVAC technicians or refrigeration service professionals. Always disconnect and lock out power to the unit before handling capacitors, as they can retain a dangerous charge even after power is removed — discharge the capacitor through a resistor before touching terminals. Confirm that the replacement MFD rating and voltage rating meet or exceed the original equipment specifications before installation. Follow applicable NEC requirements and equipment manufacturer guidelines when servicing motor capacitor circuits.
