MARS 12986 Run Capacitor
When you are out in the field and need a reliable 40/5 MFD 440V dual run capacitor that won't fail during peak summer loads, the MARS 12986 is a standard choice for condenser motors and compressors. This oval dual run capacitor is rated for 440Vac but maintains full compatibility with 370Vac systems, giving you more flexibility on your truck. Constructed with a seamless aluminum case and non-PCB oil, it facilitates efficient heat dissipation and thermal stability across a temperature range of -40°C to +70°C. The internal physical interrupter provides essential safety by disconnecting the capacitor at the end of its 60,000-hour service life or in the event of an internal fault. Designed for 50/60 Hz applications, this unit meets UL and CUL standards, ensuring it stands up to the rigorous demands of residential and commercial HVAC service.
Technical Benefits:
- Dual Capacitor Functionality: Supports both the compressor and the fan motor with 40+5 microfarad capacitance.
- Universal Voltage Rating: The 440 volt capacitor design allows it to replace 370V units without performance degradation.
- Durable Construction: High-grade aluminum housing protects against environmental corrosion in outdoor condensers.
- Terminal Configuration: Standard 1/4-inch quick-connect terminals across four posts for straightforward wiring.
- Compact Profile: The oval capacitor shape is ideal for tight electrical cabinets where space is at a premium.
Common Service Questions:
Can I use a 440V capacitor if the old one was 370V?
Yes. You can always increase the voltage rating when replacing a run capacitor, provided the capacitance (MFD) remains identical. The MARS 12986 is a common 440/370V HVAC capacitor replacement.
What are the dimensions for mounting?
The case height is 3.75 inches, with an overall height of 4.25 inches. The base measures 2.806 inches in width and 1.806 inches in depth, making it compatible with most standard oval mounting brackets.
How do I identify which terminal is which?
The terminals are clearly marked: 'HERM' for the compressor, 'FAN' for the condenser fan motor, and 'C' for the common line.
