Rectorseal M11089 Motor Start Capacitor 400-480 Mfd 220-250V

Product Description

The RECTORSEAL M11089 is a round motor start capacitor rated at 400-480 microfarads (MFD) and 220-250 volts, designed for single-phase motor starting applications in HVAC and refrigeration equipment. The phenolic construction provides durable, heat-resistant housing rated for operation between -40 and 65 degrees C. Compatible with both 50 Hz and 60 Hz systems, this capacitor delivers up to 15 starts per hour, making it suitable for the duty cycles found in residential and commercial air conditioning compressors and refrigeration units. Licensed HVAC technicians and refrigeration service pros install this part as a direct replacement when a failed start capacitor is diagnosed during system troubleshooting.

This motor start capacitor is recommended for residential and commercial AC systems and refrigeration equipment where a round, two-terminal start capacitor is required. Its wide MFD range of 400-480 and dual voltage rating of 220-250 volts allow it to serve a broad range of compressor motor applications without requiring an exact MFD match in every service situation. It is well suited for compressor motor starting circuits where momentary high-torque assistance is needed at startup.

Key Features

• 400-480 MFD rating covers a wide range of compressor motor starting requirements
• Dual voltage rating of 220-250 volts suits common single-phase compressor circuits
• Phenolic housing provides heat-resistant and durable enclosure
• Rated for up to 15 starts per hour for typical residential and commercial duty cycles
• Compatible with 50 Hz and 60 Hz electrical systems
• Round shape with 2 terminals for straightforward installation

Compatibility

Recommended for use in residential and commercial AC and refrigeration applications requiring a round, two-terminal motor start capacitor rated at 400-480 MFD and 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 removing or installing a capacitor, and discharge any stored voltage in the old capacitor before handling. Verify that the replacement MFD and voltage ratings fall within the motor manufacturer's acceptable range before completing the installation. Follow all applicable local electrical codes and equipment manufacturer guidelines during service.
