MARS 12752 Run Capacitor
The MARS 12752 Run Capacitor is a high-performance 55 MFD 440V round run capacitor engineered for PSC motor applications in demanding HVACR environments. As an industry-standard JARD round run capacitor, this unit provides the critical phase-shift required to optimize the torque and efficiency of fan motors and high-load compressors. Constructed with a non-PCB, biodegradable oil dielectric within a rugged aluminum housing, it features a patented 10,000 AFC internal physical pressure-sensitive interrupter for advanced circuit protection. This dual-voltage rated component is a reliable 440 VAC HVAC replacement capacitor that can safely substitute 370V equivalents, offering 50/60 Hz frequency compatibility. Its high-grade 1/4 inch quick-connect terminals ensure secure electrical contact, while the -40°C to +70°C operating temperature range allows for stable performance in extreme outdoor conditions, minimizing service callbacks and ensuring system longevity.
Key Benefits- Broad Replacement Compatibility: Specifically designed to replace obsolete GE/Genteq and JARD models including 12252, C355R, and 97F9042.
- Optimized Motor Performance: Maintains precise 55 microfarad capacitance with a +/- 6% tolerance to keep HVAC motors running at peak thermal efficiency.
- Safety Certified: Fully UL and CSA approved, featuring 1/4-inch male quick-disconnect terminals for rapid, standardized installation.
- Rugged Build Quality: Encased in a fluid-filled, round metal can to facilitate superior heat dissipation compared to plastic alternatives.
- Can I use this 440V capacitor if my original was rated for 370V? Yes, the 12752 is dual-rated for 370/440 VAC. You can always uprate the voltage, but never the capacitance (MFD).
- Does the physical shape (round vs. oval) matter? Yes; while electrical specs are the same, the round form factor must match your mounting bracket or strap.
- Is this suitable for both condenser fan motors and compressors? It is appropriate for any unit requiring exactly 55 MFD at 440V or 370V.
