MARS 12004 Run Capacitor
The MARS 12004 Run Capacitor is a high-performance 4 Microfarad 370Vac Oval Run Capacitor engineered specifically for continuous-duty applications in HVACR equipment. Designed to meet the precise requirements of single-phase motors, this 4 mfd 370v oval run capacitor provides the necessary phase shift to optimize motor torque and operational efficiency. As a veteran-grade HVAC replacement capacitor, the 12004 features a physical interrupter for enhanced safety, ensuring the circuit is disconnected in the event of internal pressure buildup. This MARS 12004 model is constructed with a durable aluminum case and is fully non-PCB, conforming to EIA-456 standards for 60,000 hours of operational life. Whether you are performing a preventive AC motor run capacitor swap or a critical system repair, this unit offers the mechanical reliability required for high-efficiency SEER-rated systems.
Key Benefits:
- OEM-Grade Performance: Meets or exceeds original equipment manufacturer specifications for 370V motor run capacitors.
- Safe Operation: Integrated pressure sensitive interrupter (PSI) prevents case rupture during end-of-life failure.
- Standardized Fit: Oval case design ensures compatibility with most standard mounting brackets in furnace and air handler cabinets.
- Efficient Conductivity: Equipped with 1/4 inch quick-disconnect terminals (4 terminals per post) for flexible wiring configurations.
- Reliable Lifespan: Rated for 50/60 Hz and tested to maintain capacitance stability under high-stress HVAC environments.
Common Questions:
Can I use a 440V capacitor to replace this 370V model?
Yes, in the field it is standard practice to use a higher voltage rating (like 440V) as a replacement for 370V, provided the microfarad (MFD) rating is an exact match. However, you must never use a capacitor with a lower voltage rating than specified.
How do I know if this capacitor has failed?
Technicians should look for physical signs of failure such as a "domed" or bulging top. Beyond visual inspection, use a multimeter with a capacitance setting to verify the 4 microfarad reading; any deviation greater than 10% typically necessitates replacement.
Is the oval shape critical for performance?
Electrically, oval and round capacitors with the same MFD and voltage perform identically. The oval shape is strictly a mechanical consideration to ensure the component fits within the designated mounting strap or capacitor box of the equipment.
