Description
The Mars 12731 is a round dual run capacitor rated at 35/4 microfarads (MFD) and 370 volts AC, engineered to support both the compressor and fan motor circuits in a single compact housing. Dual run capacitors are a staple in residential and light commercial HVAC systems, eliminating the need for two separate capacitors and simplifying service calls.
Key Features
- Dual capacitance rating: 35 MFD (compressor) / 4 MFD (fan motor)
- Voltage rating: 370VAC
- Round housing for easy drop-in replacement in standard capacitor brackets
- Single-unit design replaces two separate run capacitors
- Designed for use with single-phase AC motors in air conditioning and heat pump systems
- Mars brand quality construction for long service life and consistent performance
Applications
- Residential and light commercial air conditioners
- Heat pump condensing units
- Compressor and condenser fan motor circuits
Why Choose a Mars Dual Run Capacitor?
Mars capacitors are trusted by HVAC professionals for their consistent capacitance values and durable construction. The round form factor of the 12731 fits most standard mounting brackets, making it a convenient and reliable choice for field replacements. Using a properly rated dual run capacitor helps maintain motor efficiency, reduces startup strain, and extends the operational life of both the compressor and fan motor.
