Rectorseal M11044 Motor Start Capacitor 72-88 Mfd 250/220V

Product Description

The RECTORSEAL M11044 is a round motor start capacitor rated at 72-88 microfarads (MFD) and 220/250 volts, designed for single-phase motor starting applications in air conditioning and refrigeration equipment. Start capacitors provide a high-torque boost during motor startup and drop out of the circuit once the motor reaches operating speed. The phenolic construction and wide MFD range make it a practical replacement option for residential and commercial service work. Rated for operation at 50/60 Hz, it handles up to 30 starts per hour and tolerates a temperature range from -40 degrees F equivalent cold-side extremes up to 149 degrees F on the high end.

This capacitor is suited for single-phase compressor and fan motor starting circuits found in residential and commercial air conditioning systems and refrigeration equipment. HVAC technicians and refrigeration service professionals typically encounter this form factor when replacing failed start components during seasonal maintenance or emergency service calls. The round shape and dual-voltage rating of 220/250 volts allow it to fit a range of equipment without requiring an exact OEM match on voltage.

Key Features

• 72-88 MFD rating provides flexibility for multiple motor starting applications
• Dual-rated at 220/250 volts for broad equipment compatibility
• Phenolic composition for durability in high-cycle start environments
• Rated for up to 30 starts per hour
• Round shape for straightforward mounting in standard capacitor brackets
• Compatible with 50 Hz and 60 Hz systems

Compatibility

Recommended for use in residential and commercial air conditioning and refrigeration applications requiring a motor start capacitor rated 72-88 MFD at 220/250 volts.

Installation Notes

Motor start capacitors are installed by licensed HVAC technicians or refrigeration service professionals. Always disconnect and lock out power to the unit before handling any capacitor, as these components can retain a dangerous electrical charge even after power is removed. Discharge the capacitor fully using an approved bleed resistor before touching terminals. Verify that the replacement MFD rating and voltage rating meet or exceed the original equipment specification before installation.
