Rectorseal 14252 Run Capacitor 55 Mfd 440 Volt

Product Description

The RECTORSEAL 14252 is a 55 microfarad (MFD), 440-volt AC motor run capacitor built for continuous-duty applications in split-phase motor and compressor circuits. This unit is a non-polarized, oil-filled metallized polypropylene film capacitor, which provides stable capacitance under sustained load without the thermal breakdown common in dry-film designs. The 14252 is individually boxed and handled as a discrete component, making it a dependable replacement choice for HVAC technicians working on residential and light-commercial equipment. Its 440-volt rating gives it voltage headroom suitable for use on both 208-volt and 240-volt motor circuits.

This capacitor is intended for split-phase motors, compressor start-assist and run circuits, fan motors, and general AC filter applications. It sees regular use in condensing units, air handlers, and packaged rooftop equipment where a high-capacitance run capacitor is required to maintain motor torque and power factor. HVAC service technicians are the primary installers, though licensed electricians servicing motor-driven equipment will encounter this component as well.

Key Features

• 55 MFD capacitance rated for continuous AC motor run duty
• 440-volt rating accommodates 208-volt and 240-volt motor circuits
• Non-polarized construction — no orientation requirement during installation
• Oil-filled metallized polypropylene film dielectric for thermal stability under sustained load
• Individually boxed for discrete component handling and inventory
• Suitable for compressor, fan motor, filter, and other split-phase AC applications

Compatibility

Designed as an OEM-style replacement run capacitor for residential and light-commercial HVAC compressor and fan motor applications requiring a 55 MFD, 440-volt non-polarized run capacitor.

Installation Notes

Run capacitors must be installed by a qualified HVAC technician or licensed electrician. Disconnect and lock out all power to the unit before servicing capacitors — capacitors store a charge and must be safely discharged before handling. Verify that the replacement capacitor MFD and voltage ratings match or exceed the original equipment specification before installation. Follow all applicable NEC requirements and local codes when servicing motor circuits.
