Rectorseal M11053 Motor Start Capacitor 233-292 Mfd 250V

Product Description

The RECTORSEAL M11053 is a round motor start capacitor rated at 233-292 microfarads (MFD) and 220/250 volts, designed for single-phase motor starting applications in air conditioning and refrigeration systems. The phenolic construction provides resistance to heat and moisture common in mechanical equipment rooms and outdoor condenser environments. Rated for operation from -40 degrees F to 149 degrees F (equivalent to -40 to 65 degrees C), this capacitor handles wide temperature swings without degraded performance. It supports both 50 Hz and 60 Hz systems and allows up to 15 starts per hour, making it suitable for equipment with frequent cycling demands. Licensed HVAC technicians and refrigeration service pros are the primary installers.

The M11053 is recommended for use in residential and commercial air conditioning systems as well as refrigeration equipment. The 233-292 MFD range accommodates motors with varying start torque requirements across that capacitance window. The dual voltage rating of 220/250 volts makes it compatible with both standard residential and light commercial supply voltages. Two terminals accommodate typical motor start wiring configurations found on compressors and condenser fan motors throughout the HVAC and refrigeration trades.

Key Features

• 233-292 MFD capacitance range for flexible motor starting across that window
• Dual voltage rating: 220/250 volts for residential and commercial supply compatibility
• Phenolic composition for heat and moisture resistance
• Wide operating temperature range: -40 to 65 degrees C
• Supports up to 15 starts per hour for frequently cycling equipment
• Compatible with 50 Hz and 60 Hz systems
• Round shape with 2-terminal configuration for standard motor start wiring

Compatibility

Designed for use in residential and commercial air conditioning and refrigeration applications requiring a motor start capacitor rated at 233-292 MFD and 220/250 volts with a round, 2-terminal form factor.

Installation Notes

Motor start capacitors are installed by licensed HVAC technicians and refrigeration service professionals. Always disconnect and lock out power to the unit before handling capacitors, and discharge any stored charge using an approved resistor discharge tool before removal. Verify that the replacement MFD rating and voltage rating meet or exceed the original equipment specifications before installation. Work must comply with applicable local electrical codes and NEC requirements.
