Description
The Mars 12783 is a high-quality round dual run capacitor engineered to deliver dependable performance in residential and light commercial HVAC systems. Rated at 35/5 microfarads and 440VAC, this dual run capacitor supports both the compressor and the condenser fan motor simultaneously from a single, compact unit — simplifying installation and reducing the number of components needed in the system.
Key Features
- Dual run capacitor — supports compressor and fan motor in one unit
- Capacitance rating: 35/5 microfarads (MFD/µF)
- Voltage rating: 440VAC
- Round form factor for easy, space-saving installation
- Designed as a direct replacement for failed or degraded OEM capacitors
- Compatible with a wide range of air conditioning and heat pump systems
Why Choose a Dual Run Capacitor?
Dual run capacitors combine two capacitors in a single housing, providing the starting and running torque needed for both the compressor and the condenser fan motor. This design reduces wiring complexity and saves space inside the electrical compartment. The Mars 12783 is built to maintain consistent capacitance over time, helping to extend motor life and improve overall system efficiency.
Typical Applications
- Central air conditioning condensing units
- Heat pump systems
- Residential and light commercial HVAC equipment
- Compressor and condenser fan motor circuits
Installation Notes
Always discharge the capacitor before handling. Verify the capacitance and voltage ratings match the equipment nameplate specifications before installation. The round housing is designed for standard capacitor brackets and mounting hardware.
