Rectorseal M11034 Motor Start Capacitor 189-227 Mfd 165V

Product Description

The RECTORSEAL M11034 is a round motor start capacitor rated at 189-227 microfarads (MFD) and 165 volts, designed to provide the starting torque needed to get single-phase compressor and fan motors up to operating speed. Built with a phenolic composition housing, this capacitor handles a rated temperature range of -40 degrees F to 149 degrees F (-40 to 65 degrees C) and supports up to 30 starts per hour. It is installed by licensed HVAC technicians and refrigeration mechanics during equipment commissioning, component replacement, or motor start circuit troubleshooting. The two-terminal, round form factor suits a wide range of residential and commercial motor start applications.

The M11034 is rated for use in residential and commercial air conditioning systems and refrigeration equipment. It is a common replacement choice when a failed or weak start capacitor is identified during a service call on single-phase motor-driven systems. The 50/60 Hz compatibility makes it suitable for standard North American electrical systems. Its MFD range of 189-227 provides flexibility in matching the capacitance requirement specified on the motor nameplate.

Key Features

• 189-227 MFD rating accommodates a range of motor start capacitance requirements
• 165-volt operating voltage for motor start circuit applications
• Phenolic housing construction rated for -40 to 65 degrees C operating range
• Supports up to 30 starts per hour for high-cycle applications

Compatibility

Rated for residential and commercial air conditioning and refrigeration applications. Designed as an OEM-style motor start capacitor replacement for single-phase compressor and fan motor circuits where a 189-227 MFD, 165-volt start capacitor is specified.

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 capacitors, and discharge any stored voltage from the old capacitor using a properly rated discharge tool before removal. Verify the replacement MFD value falls within the range printed on the motor nameplate before installation. Follow applicable NEC requirements for wiring and component replacement within the equipment enclosure.
