Rectorseal M11036 Motor Start Capacitor 270-324 Mfd 165V

Product Description

The RECTORSEAL M11036 is a round motor start capacitor rated at 270-324 microfarads (MFD) and 165 volts, designed to provide the starting torque boost required by single-phase compressor and fan motors in air conditioning and refrigeration equipment. Built with a phenolic composition, it operates across a wide temperature range from -40 degrees F to 149 degrees F (65 degrees C max), making it suitable for installations exposed to temperature extremes. Rated for 50/60 Hz systems, this capacitor supports up to 20 starts per hour. HVAC technicians and refrigeration service pros install this part as a direct replacement when a failed start capacitor prevents motor startup or causes slow, labored motor starts.

This motor start capacitor is intended for residential and commercial air conditioning and refrigeration applications. It is commonly installed in systems where single-phase motors require a high-capacitance start boost to achieve full operating speed. Typical use cases include compressor motor start circuits in split-system air conditioners, package units, and commercial refrigeration equipment. The two-terminal, round form factor fits standard capacitor mounting brackets and discharge configurations found in most equipment cabinets.

Compatibility

Designed for use in residential and commercial air conditioning and refrigeration systems requiring a 270-324 MFD, 165-volt motor start capacitor.

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, and discharge the capacitor fully before removal using an approved discharge tool, as start capacitors can retain a dangerous charge after power is removed. Verify the replacement MFD range and voltage rating match the equipment nameplate specifications before installation. Follow applicable NEC guidelines and local codes when servicing electrical components inside equipment cabinets.
