Rectorseal M11072 Motor Start Capacitor 815-970 Mfd 110/125V

Product Description

The RECTORSEAL M11072 is a round motor start capacitor rated at 815-970 microfarads (MFD) and 110/125 volts, designed to provide the high-torque starting boost that single-phase induction motors require during startup. Built with a phenolic composition and rated for operation from -40 degrees F to 149 degrees F (65 degrees C), this capacitor handles the thermal stress of demanding HVAC and refrigeration environments. It operates on both 50 Hz and 60 Hz systems and supports up to 15 starts per hour, making it a reliable choice for applications with frequent cycling. Licensed technicians working on air conditioning and refrigeration equipment will find this a straightforward OEM-style replacement.

This capacitor is suited for residential and commercial air conditioning systems and refrigeration equipment where a motor start capacitor is required to bring compressor or fan motors up to operating speed. Its 110/125-volt rating covers the supply voltages common in single-phase residential and light commercial installations. The round form factor and two-terminal configuration fit the majority of standard motor start capacitor mounting arrangements found in condensing units, refrigeration compressors, and related equipment.

Compatibility

Designed for use in residential and commercial air conditioning and refrigeration systems requiring a motor start capacitor rated at 815-970 MFD and 110/125 volts.

Installation Notes

Motor start capacitors are installed by licensed HVAC technicians or refrigeration mechanics. Always disconnect and lock out power to the unit before servicing capacitors, and discharge any stored charge using an appropriate discharge resistor before handling. Verify that the replacement MFD range and voltage rating meet or exceed the original equipment specification before installation. Work should comply with applicable NEC requirements and local electrical codes.
