MARS 12715 Run Capacitor

For service technicians requiring a reliable 25 MFD 370V run capacitor, the MARS 12715 provides a high-spec solution for single-phase 50/60 Hz motor applications. Engineered as a direct replacement for S1-024-23181-000, this high-performance component is built to sustain the inductive loads of residential HVAC condensing units, air handlers, and refrigeration compressors. The MARS 12715 features a robust round aluminum case design, utilizing a non-PCB, oil-filled dielectric to ensure stable heat dissipation in high-ambient environments. This HVAC motor run capacitor is rated for continuous duty with an operating temperature range of -40°C to +70°C and meets EIA-456-A standards. Safety is managed via an internal pressure-sensitive interrupter designed to disconnect the capacitor in the event of an internal fault, preventing case rupture. With standard 1/4 inch male quick-connect terminals, this 25 microfarad unit ensures a fast, secure fit during field service or AC capacitor replacement.

• Precision Capacitance: Maintains a steady 25 microfarad output to optimize motor torque and efficiency.
• Direct OEM Cross-Reference: Validated as the functional equivalent for S1-024-23181-000 and similar 370VAC 25 uF units.
• Industrial-Grade Build: Features a rolled aluminum shell and 10,000 AFC protection for maximum field reliability.
• Broad Compatibility: Suitable for use in both 370V and lower voltage applications where a round form factor is required.

• Can I use a 370V capacitor if my original was 440V? No. You can always go up in voltage (using 440V to replace 370V), but you should never go down. This 370V unit is specifically for systems rated at 370V or lower.
• Does the "Round" shape matter compared to "Oval"? If the MFD and Voltage match, they are electrically interchangeable, provided your mounting bracket can accommodate the round 1.75-inch diameter.
• How do I know if the unit is failing? Look for physical bulging at the top of the canister, oil leaks, or a microfarad reading that falls more than 6% below the 25 MFD rating on your multimeter.
