Rectorseal m11049 Motor Start Capacitor 145-175 Mfd 250 220V

Product Description

The RECTORSEAL m11049 is a round motor start capacitor rated 145-175 MFD at 220/250 volts, designed to provide the high starting torque needed to bring compressor and fan motors up to operating speed in AC and refrigeration systems. Built with a phenolic composition housing, this capacitor handles a temperature range from -40 degrees F to 149 degrees F (65 degrees C max) and supports up to 20 starts per hour. It is a direct-replacement style unit suited for service technicians performing capacitor swaps on single-phase motor applications in both residential and light commercial installations.

The m11049 is recommended for residential and commercial air conditioning and refrigeration equipment where a motor start capacitor in the 145-175 MFD range is required. It operates on 50/60 Hz systems at 220 or 250 volts, making it compatible with standard North American single-phase power configurations as well as equipment rated for lower voltage tiers. HVAC and refrigeration technicians typically install this part during compressor or condenser fan motor service calls when a failed or weak start capacitor is identified as the root cause.

Key Features

• 145-175 MFD rating covers a wide range of motor start requirements
• Dual voltage rating of 220/250V supports flexible application across equipment
• Phenolic composition housing for durability in service conditions
• Round shape for straightforward mounting in standard capacitor brackets
• Rated for up to 20 starts per hour, suitable for cycling residential and commercial systems
• Wide temperature range: -40 degrees F minimum to 149 degrees F maximum operating

Compatibility

Recommended for use in residential and commercial AC and refrigeration equipment requiring a motor start capacitor in the 145-175 MFD, 220/250V range on 50/60 Hz systems.

Installation Notes

Motor start capacitors must be installed by a qualified HVAC or refrigeration technician. Disconnect and lock out all power to the unit before handling any capacitor, and discharge the existing capacitor fully before removal, as residual charge can cause serious injury. Match the MFD rating and voltage rating of the replacement to the equipment nameplate requirements. Secure the capacitor in a proper bracket and ensure terminal connections are tight and insulated before restoring power.
