MARS 12754 Run Capacitor

The MARS 12754 Run Capacitor is a heavy-duty, professional-grade solution for residential and commercial HVACR motor applications. This 60 microfarad 440Vac round run capacitor is designed to improve motor power factor and reduce phase shift, ensuring your compressor or fan motor operates at peak electrical efficiency. Built with a robust aluminum casing and a steel cap, this 60 MFD 440V capacitor is oil-filled and non-PCB for reliable heat dissipation and long-term stabilization. As a round motor run capacitor, it serves as a direct replacement for many OEM units, specifically engineered to handle the constant cycling and electrical stresses found in modern high-efficiency air conditioning and refrigeration systems. This HVAC replacement capacitor is dual-rated for 370V and 440V applications, providing tactical flexibility for service technicians managing diverse equipment on-site. Field-tested for durability, the MARS 12754 ensures consistent torque and assists in maintaining lower motor operating temperatures, which is critical for preventing premature winding failure.

• Universal Compatibility: Works as a drop-in replacement for any 60 MFD 440V or 370V round capacitor.
• Enhanced Thermal Stability: Oil-filled design manages heat during high-demand cooling cycles.
• Internally Protected: Features a 10,000 AFC safety pressure interrupter to prevent casing rupture.
• Precision Tolerance: Tight capacitance tolerances ensure the motor stays within its designated amp draw.

Can I use a 440V capacitor to replace a 370V unit?
Yes, you can always go up in voltage when replacing a capacitor. The MARS 12754 is dual-rated at 440V, making it a safe and superior upgrade for 370V systems.

What are the signs that a 60 MFD capacitor is failing?
Typical failure indicators include a bulging top, visible oil leaks, or "hard starting" where the motor hums but fails to spin. Measuring it with a multimeter often reveals a reading significantly lower than the rated 60 microfarads.

Will this work for both the fan and the compressor?
This is a single-value run capacitor. If your unit uses a dual run capacitor (e.g., 60+5 MFD), you would use this for the 60 MFD side or paired with a separate fan capacitor. Check your motor nameplate for specific microfarad ratings.
