MARS 12795 Run Capacitor

The MARS 12795 is a high-performance 60/7.5 MFD 440V Round Dual Run Capacitor engineered for continuous-duty operation in demanding residential and light commercial HVACR systems. Designed to support both the compressor and the condenser fan motor, this Jard by Mars component features a dual-rated voltage capacity, making it a reliable field replacement for both 370V and 440V capacitor applications. The 60+7.5 microfarad rating ensures steady torque and electrical phase shift, essential for maintaining the SEER efficiency of modern air conditioning and refrigeration equipment.

Constructed within a rugged, seamless aluminum case, the MARS 12795 utilizes a non-PCB, metallized polypropylene dielectric film to maintain capacitance stability across a broad thermal operating range of -40°C to 70°C. This HVAC dual run capacitor is equipped with quad 1/4-inch quick-connect terminals for flexible wiring configurations and includes an internal physical interrupter for critical pressure protection. Meeting EIA-456-A and Tecumseh H-115 industry standards, it serves as an excellent OEM equivalent capacitor for contractors requiring a high-uptime solution for motor-start assistance and run-cycle stabilization.

• Dual Voltage Compatibility: Rated for both 370 VAC and 440 VAC applications, reducing the variety of stock needed on the service truck.
• Enhanced Dielectric Strength: Built with high-grade metallized polypropylene film to withstand electrical surges and minimize thermal degradation.
• Universal Round Form Factor: Standard 2-inch diameter and 4.75-inch case height ensure compatibility with most existing blower and condenser motor brackets.
• Safety Integrated: Features a built-in pressure-sensitive interrupter designed to disconnect the capacitor in the event of an internal failure.
• High Temperature Resilience: Rated for 60,000 hours of operational life at temperatures up to 70°C, meeting strict HVACR environmental specs.

Can I use this 440V capacitor to replace a 370V unit?
Yes. A higher voltage rating is always acceptable for replacement as long as the microfarad (MFD) ratings match the original motor specifications. It provides a larger safety margin against voltage spikes.

What happens if the capacitance drops below the ±6% tolerance?
If the MFD rating drifts too far, the compressor or fan motor will draw higher amperage, leading to overheating, shortened motor life, and potential start-cycle failure.

Are the four-blade terminals compatible with single-wire connections?
Absolutely. The quad-terminal design allows for multiple leads (e.g., C, HERM, FAN) to be connected to the same terminal bank, facilitating easier jumps or complex wiring in the field.
