Description
The Mars 12386 is a 4 Microfarad (MFD), 450VAC run capacitor engineered specifically for mini-split HVAC systems. Designed to maintain a continuous charge during motor operation, this run capacitor ensures consistent torque, smooth startup, and efficient running performance for single-phase fan and compressor motors found in ductless mini-split applications.
Key Features
- Capacitance: 4 Microfarad (MFD/µF)
- Voltage Rating: 450VAC — suitable for use in systems rated at or below 450VAC
- Designed specifically for mini-split HVAC systems
- Compact form factor for easy installation in space-constrained equipment
- Provides stable capacitance to support reliable motor operation
- Helps maintain motor efficiency and extend equipment service life
Application
This run capacitor is ideal for servicing and replacing worn or failed capacitors in ductless mini-split systems. Run capacitors remain energized throughout motor operation, supplying the phase shift needed to keep single-phase motors running smoothly and efficiently. A failed run capacitor is a common cause of motor overheating, reduced efficiency, and compressor or fan motor failure — making the Mars 12386 an essential stock item for any HVAC technician servicing mini-split equipment.
