Value Collection 12933 Motor Run Capacitor 12.5 Mfd

Product Description

The VALUE COLLECTION 12933 is a motor run capacitor rated at 12.5 microfarads (MFD) and 440 volts, designed to support the start and run cycles of single-phase AC motors in HVAC and light commercial equipment. Motor run capacitors maintain a continuous phase-shifted current to the auxiliary winding of a motor, improving torque, efficiency, and motor longevity. This capacitor measures 2.16 inches wide by 1.31 inches deep by 3.75 inches high and weighs approximately 0.41 pounds, making it a compact replacement for failed or degraded OEM units. It is typically installed by HVAC technicians servicing fan motors, blower motors, or compressors.

This capacitor is suited for residential and light commercial HVAC applications where a 12.5 MFD, 440-volt run capacitor is required. Common install scenarios include replacing a failed run capacitor on a condenser fan motor, blower motor, or other single-phase induction motor. The 440-volt rating provides a safety margin over standard 370-volt applications, making it an acceptable substitute in many 370-volt-rated motor circuits as well.

Key Features

• 12.5 MFD capacitance for precise motor run support
• 440-volt rating suitable for both 370-volt and 440-volt motor circuits
• Compact form factor: 2.16 inches wide by 1.31 inches deep by 3.75 inches high
• Lightweight at approximately 0.41 pounds for easy handling in tight equipment cabinets
• Single-unit packaging with a minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement run capacitor for single-phase AC motors in residential and light commercial HVAC equipment requiring a 12.5 MFD, 440-volt rated capacitor.

Installation Notes

Motor run capacitors are installed by licensed HVAC technicians. Always disconnect and lock out power to the unit before servicing capacitors, as capacitors can retain a dangerous charge even after power is removed — discharge the capacitor safely before handling. Verify the MFD rating and voltage rating of the replacement match or exceed the original equipment specification. Follow all applicable local electrical codes and NEC guidelines when replacing capacitors in HVAC equipment.
