Rectorseal M11041 Motor Start Capacitor 36-43 Mfd 250V

Product Description

The RECTORSEAL M11041 is a round motor start capacitor rated at 36-43 microfarads (MFD) and 220/250 volts, designed for single-phase motor starting duty in air conditioning and refrigeration systems. The phenolic composition housing provides durable enclosure for the capacitor element. Rated for 50/60 Hz service, the M11041 supports up to 60 starts per hour and operates across a wide temperature range of -40 to 65 degrees C, making it suitable for demanding installation environments. Two-terminal construction simplifies wiring during replacement service.

This capacitor is engineered for residential and commercial air conditioning and refrigeration applications where motor start duty is required. It is a common replacement component in compressor and blower motor circuits that require a start capacitor to deliver the initial torque needed to bring the motor up to running speed. HVAC technicians and refrigeration service professionals typically encounter this capacitor in condensing units, fan coil assemblies, and light commercial refrigeration equipment.

Key Features

• 36-43 MFD rating accommodates a range of motor starting requirements
• Dual-rated for 220 and 250 volt systems for flexible application
• Round phenolic housing provides durable, impact-resistant enclosure
• Supports up to 60 starts per hour for high-cycle applications
• Wide operating temperature range: -40 to 65 degrees C
• 50/60 Hz compatible for broad system compatibility

Compatibility

Designed for use in residential and commercial air conditioning and refrigeration systems requiring a round, two-terminal motor start capacitor rated at 36-43 MFD and 220/250 volts.

Installation Notes

Motor start capacitors are replaced by qualified HVAC technicians or refrigeration service professionals. Disconnect and lock out all power to the unit before handling capacitors, as they can retain a dangerous charge even after power is removed. Discharge the capacitor safely using a resistive discharge tool before touching terminals. Verify that the replacement MFD rating and voltage rating meet or exceed the failed component specifications before energizing the system.
