Mars tp-cap-10/440usa Oval Run Capacitor 10 Mfd 440V

Product Description

The MARS tp-cap-10/440usa is a single-run oval capacitor rated at 10 microfarads (MFD) and 440 volts, designed for use in HVAC motor circuits. Run capacitors maintain a continuous phase shift in motor windings to keep single-phase motors running efficiently under load. This unit is sold individually and is a direct replacement for failed or weak run capacitors found in residential and light commercial HVAC equipment. Licensed HVAC technicians are the primary installers for this component during seasonal tune-ups, motor replacement jobs, or system diagnostics.

This capacitor is suited for single-phase condenser fan motors and compressor run circuits commonly found in residential central air conditioning systems and heat pumps. It is a standard oval-style form factor, which fits most OEM capacitor brackets without modification. The 440-volt rating makes it compatible with both 370-volt and 440-volt applications, offering flexibility across a wide range of equipment age and vintage.

Key Features

• 10 MFD capacitance rating for single-run motor circuit applications
• 440-volt rating covers both 370V and 440V system requirements
• Oval form factor fits standard OEM capacitor mounting brackets
• Sold individually (each) for single-unit replacement jobs
• Manufacturer alternate part number: TP10440UO

Compatibility

Designed as an OEM-style replacement run capacitor for single-phase condenser fan motors and compressor circuits in residential and light commercial HVAC systems requiring a 10 MFD, 440-volt oval capacitor.

Installation Notes

Run capacitors must be installed by a licensed HVAC technician. Before servicing, disconnect and lock out all power to the unit and discharge the capacitor fully using an appropriate resistive discharge tool — never short capacitor terminals directly. Verify the MFD rating and voltage rating of the original capacitor before installing the replacement. Comply with all local electrical codes and manufacturer wiring diagrams when reconnecting terminals.
