Rectorseal M11071 Motor Start Capacitor 430-516 Mfd 110/125V

Product Description

The RECTORSEAL M11071 is a round motor start capacitor rated at 430 to 516 microfarads (MFD) and 110/125 volts, designed to provide the high-torque starting current needed to bring single-phase compressor and fan motors up to operating speed. Built with a phenolic composition housing, this capacitor handles a broad temperature range from -40 degrees F to 149 degrees F (65 degrees C max), making it suitable for demanding installation environments. It operates at 50/60 Hz and supports up to 20 starts per hour, meeting the duty cycles common in air conditioning and refrigeration applications.

This motor start capacitor is recommended for use in residential and commercial air conditioning systems and refrigeration equipment. It is a standard round two-terminal unit, appropriate for installations where a start capacitor is required to assist single-phase motors during startup. HVAC technicians and refrigeration service pros will encounter this type of capacitor in compressor circuits and condenser fan motor assemblies across a wide range of system sizes.

Compatibility

Recommended for residential and commercial air conditioning and refrigeration systems requiring a motor start capacitor rated at 430-516 MFD and 110/125 volts.

Installation Notes

Motor start capacitors are installed by licensed HVAC technicians or qualified refrigeration service professionals. Always disconnect and lock out power to the unit before servicing capacitor circuits, as capacitors can retain a dangerous charge even after power is removed — discharge safely using an approved resistor or capacitor discharge tool before handling. Verify that the replacement MFD rating and voltage rating match or are within the acceptable range specified by the motor manufacturer before installation. Follow applicable NEC guidelines and local codes when performing electrical service on HVAC and refrigeration equipment.
