The Mars 12201 is a round dual run capacitor rated at 80/10 microfarads (MFD) and 370VAC, engineered to keep residential and light commercial air conditioning systems running at peak efficiency. Dual run capacitors serve two critical functions in a single compact unit — simultaneously supporting the compressor and the condenser fan motor — making them an essential component for reliable HVAC system operation.
Key Features
- Dual capacitance rating: 80/10 microfarads (MFD)
- Voltage rating: 370VAC
- Round form factor for easy, space-saving installation
- Supports both compressor and condenser fan motor in a single unit
- Designed as a direct replacement for failed or degraded run capacitors
- Compact design fits standard capacitor brackets and housings
Why Use a Dual Run Capacitor?
Dual run capacitors combine two capacitors into one housing, reducing installation complexity and saving valuable space inside the condensing unit. The 80 MFD side powers the compressor motor, while the 10 MFD side supports the condenser fan motor. When a run capacitor fails, motors may struggle to start, run inefficiently, or fail entirely — making timely replacement critical to system longevity.
Application
- Residential and light commercial air conditioning systems
- Condenser unit compressor motor support
- Condenser fan motor support
- Replacement for worn or failed OEM dual run capacitors
