Rectorseal m11066 Run Capacitor 145-175 Mfd 330V

Product Description

The RECTORSEAL m11066 is a run capacitor rated at 145 to 175 microfarads (MFD) and 330 volts, designed to support motor starting and running performance in HVAC equipment. Run capacitors maintain a continuous phase shift in single-phase motor windings, allowing the motor to operate efficiently under load. This capacitor is installed by licensed HVAC technicians during routine service calls or compressor and blower motor replacements. Its compact cylindrical form factor fits standard capacitor mounting brackets found in most residential and light commercial equipment.

This capacitor is suited for use in single-phase HVAC systems where a high-MFD run capacitor is required. The 145 to 175 MFD rating covers a range of motor applications, making it a versatile service part for technicians stocking a general replacement inventory. It is appropriate for compressor, condenser fan motor, or blower motor circuits operating on 330-volt-rated capacitor terminals.

Key Features

• Rated 145 to 175 MFD for broad motor application coverage
• 330-volt rating suitable for single-phase HVAC motor circuits
• Compact footprint: 2.06 x 2.06 x 4.38 inches
• Cylindrical form factor fits standard capacitor mounting hardware
• Designed as a service replacement for run capacitor applications

Compatibility

Designed as an OEM-style replacement run capacitor for single-phase residential and light commercial HVAC systems requiring a 145 to 175 MFD, 330-volt rated capacitor.

Installation Notes

Run capacitors must be replaced by a licensed HVAC technician. Always disconnect and lock out power to the unit before servicing the capacitor compartment. Capacitors store a high-voltage charge even after power is removed — discharge the capacitor safely using an insulated resistor or approved discharge tool before handling. Verify the MFD rating and voltage rating match the motor nameplate requirements before installation.
