Rectorseal m11028 Motor Start Capacitor 708-850 Mfd 110/125V

Product Description

The RECTORSEAL m11028 is a motor start capacitor rated at 708-850 microfarads (MFD) and 110/125 volts, designed to provide the high initial torque needed to start single-phase compressor and fan motors in HVAC and refrigeration systems. Built with a phenolic composition in a round form factor, this capacitor is rated for operation from -40 degrees F to 149 degrees F (65 degrees C max), making it suitable for a wide range of service environments. It operates at 50/60 Hz and supports up to 15 starts per hour, which is standard for residential and light commercial cycling equipment.

This start capacitor is intended for use in residential and commercial air conditioning systems and refrigeration equipment. It is a drop-in style replacement commonly installed during compressor hard-start troubleshooting or scheduled capacitor replacement. HVAC technicians and refrigeration service pros typically install this part when a compressor fails to start, draws high locked-rotor amperage, or trips breakers on startup. The 708-850 MFD range accommodates motor start applications where a wide-tolerance capacitor is acceptable per the equipment manufacturer's specification.

Key Features

• 708-850 MFD rating covers a broad range of motor start requirements
• Rated for 110/125 volts at 50/60 Hz for domestic and international frequency compatibility
• Phenolic composition construction for durability in service conditions
• Round form factor for easy fitment in standard capacitor mounts
• Supports up to 15 starts per hour, consistent with residential and commercial duty cycles
• Wide temperature range from -40 degrees F to 149 degrees F (65 degrees C)

Compatibility

Designed for use in residential and commercial air conditioning and refrigeration equipment requiring a motor start capacitor in the 708-850 MFD range at 110/125 volts.

Installation Notes

Motor start capacitors are installed by licensed HVAC technicians or qualified refrigeration mechanics. Always disconnect and lock out power to the unit before servicing capacitors, and discharge any stored voltage using an insulated resistor or rated discharge tool before handling. Verify that the replacement MFD rating and voltage rating meet or exceed the equipment manufacturer's specifications before installation. Follow applicable NEC and local electrical code requirements for safe service and reconnection.
