Supco lcr5x440 Run Capacitor 5 Mfd 440V Oval

Product Description

The SUPCO lcr5x440 is a single-run capacitor rated at 5 microfarads (MFD) and 440 volts, designed for continuous-duty motor run applications in HVAC equipment. The oval polypropylene foil housing measures 2.03 inches wide, 1.24 inches deep, and 1.57 inches tall, making it a compact drop-in form factor for tight equipment compartments. A standard tolerance of plus or minus 5 percent and a foil thickness of 6 micrometers support consistent electrical performance across the rated temperature range. Licensed HVAC technicians install this capacitor in split systems, package units, and other motor-driven HVAC equipment where a run capacitor maintains phase shift and steady motor torque during operation.

This run capacitor is suited for residential and light commercial HVAC applications where a single oval capacitor powers a condenser fan motor or compressor. The 440-volt rating covers both 370-volt and 440-volt systems, giving technicians flexibility when replacing failed capacitors in the field. Its compact oval body fits standard capacitor brackets and retaining straps commonly found in outdoor condensing units and air handlers.

Key Features

• 5 MFD capacitance with plus or minus 5 percent standard tolerance
• 440-volt rating compatible with 370-volt and 440-volt motor circuits
• Oval polypropylene foil housing resists moisture and heat in outdoor enclosures
• Wide operating temperature range of -40 to 185 degrees F for reliable year-round performance
• Compact dimensions — 2.03 inches wide, 1.24 inches deep, 1.57 inches tall — fit tight equipment compartments
• 6-micrometer foil thickness supports stable capacitance under continuous load

Compatibility

Designed as an OEM-style replacement run capacitor for residential and light commercial HVAC systems requiring a single oval 5 MFD, 440-volt capacitor.

Installation Notes

Capacitor replacement is performed by a licensed HVAC technician. Always disconnect and lock out power to the unit before opening the electrical compartment, and discharge the existing capacitor using an insulated discharge tool before handling — capacitors can store a lethal charge even after power is removed. Verify that the replacement MFD rating and voltage rating meet or exceed the equipment nameplate specifications before installation. Secure the capacitor in its bracket or strap to prevent vibration damage during operation.
