Value Collection 12949 Motor Run Capacitor 50 Mfd 440V

Product Description

The VALUE COLLECTION 12949 is a motor run capacitor rated at 50 microfarads (MFD) and 440 volts, designed to support the starting and running of single-phase AC motors in HVAC and related mechanical systems. Motor run capacitors maintain a continuous phase shift in the motor winding circuit, improving torque, efficiency, and power factor during operation. At 2.91 inches wide, 1.91 inches deep, and 4.75 inches high, this capacitor fits common oval or round capacitor mounting brackets. It weighs 0.7 pounds. HVAC technicians and electricians install this type of component during routine maintenance or when diagnosing a motor that runs hot, hums without starting, or fails to reach full speed.

This capacitor is suited for single-phase PSC (permanent split capacitor) motors found in condenser fan motors, blower motors, and compressors in residential and light commercial HVAC equipment. It is a common replacement item during seasonal maintenance or unplanned service calls when a failed capacitor is identified as the cause of motor performance issues. The 440-volt rating provides compatibility across a wide range of equipment that may operate on either 370-volt or 440-volt rated circuits, as higher-rated capacitors are generally acceptable in lower-voltage applications per standard HVAC practice.

Key Features

• 50 MFD capacitance rating for high-torque single-phase motor support
• 440-volt rating suitable for use across 370V and 440V motor circuits
• Compact form factor at 2.91 x 1.91 x 4.75 inches for straightforward bracket mounting
• Lightweight at 0.7 pounds for easy handling during service calls
• Single-unit packaging suitable for per-unit replacement inventory

Compatibility

Designed as a general-purpose OEM-style replacement motor run capacitor for single-phase PSC motors in residential and light commercial HVAC systems requiring a 50 MFD, 440-volt run capacitor.

Installation Notes

Motor run capacitors must be installed by a qualified HVAC technician or licensed electrician. Always disconnect and lock out power to the unit before handling capacitors, as they retain a dangerous charge even after power is removed — discharge the capacitor safely using an approved discharge tool before handling terminals. Verify the replacement MFD and voltage rating match or exceed the original equipment specification before installation. Follow all applicable NEC guidelines when servicing electrical components in HVAC equipment.
