Value Collection 12945 Motor Run Capacitor 40 Mfd

Product Description

The VALUE COLLECTION 12945 is a single-section motor run capacitor rated at 40 microfarads (MFD) and 440 volts. Motor run capacitors maintain a phase shift in the auxiliary winding of single-phase motors throughout operation, providing consistent torque and efficient motor performance. This unit measures 2.91 inches wide by 1.91 inches deep by 4.75 inches high and weighs 0.7 pounds. HVAC technicians and refrigeration mechanics install these capacitors in condenser fan motors, compressor circuits, and air handler blower motors where continuous-duty capacitance is required.

This capacitor is suited for residential and light commercial HVAC applications. Common installation scenarios include replacing failed or out-of-tolerance run capacitors in condenser units, rooftop package units, and air handler assemblies. The 440-volt rating allows it to be used in both 208-volt and 240-volt single-phase motor circuits, making it a practical service replacement for a broad range of motor sizes encountered in the field.

Key Features

• 40 MFD capacitance rating for motor run applications
• 440-volt rating compatible with 208V and 240V single-phase circuits
• Compact form factor: 2.91 inches wide by 1.91 inches deep by 4.75 inches high
• Lightweight at 0.7 pounds for easy handling in confined equipment compartments
• Single-section design for straightforward installation

Compatibility

Designed as an OEM-style replacement motor run capacitor for single-phase condenser fan motors, blower motors, and compressor circuits requiring a 40 MFD, 440-volt run capacitor.

Installation Notes

Motor run capacitors must be installed by a qualified HVAC technician or electrician. Disconnect and lock out all power to the unit before servicing any capacitor — capacitors store a lethal charge and must be safely discharged before handling. Verify the replacement capacitor matches the MFD rating and voltage rating on the original nameplate. Follow applicable NEC guidelines for electrical component replacement in motor circuits.
