Description
The Mars 12119 is a 35/6 Microfarad (MFD), 440VAC round dual run capacitor engineered to deliver dependable starting and running performance for residential and light commercial HVAC systems. By combining two capacitance values into a single compact round housing, this dual run capacitor simultaneously supports both the compressor and the condenser fan motor — reducing component count and simplifying installation.
Key Features
- Dual capacitance rating: 35/6 Microfarad (MFD/µF)
- Voltage rating: 440VAC — compatible with standard 370VAC and 440VAC applications
- Round housing for easy drop-in replacement in most capacitor brackets
- Supports simultaneous compressor and condenser fan motor operation
- Designed for residential and light commercial air conditioning and heat pump systems
- Mars quality construction for long service life and reliable performance
Application
Dual run capacitors are essential components in air conditioning and heat pump systems. The 35 MFD side powers the compressor motor while the 6 MFD side supports the condenser fan motor, ensuring both motors start and run efficiently. The 440VAC rating provides added voltage headroom, making this capacitor a dependable upgrade or direct replacement in a wide range of systems.
