The MARS 12885 is a professional-grade 35/5 MFD 440V Oval Run Capacitor designed for continuous duty in residential and light commercial HVAC systems. This dual run capacitor serves as a reliable replacement for condenser fan motors and compressor start-run circuits, ensuring optimal power factor correction and motor torque. Rated for 440 VAC, it is backward compatible with 370V applications, providing technicians with a versatile solution for varying field requirements. The oval dual capacitor design allows for a compact footprint in tight electrical cabinets, while the high-quality microfarad rating (+/- 6% tolerance) maintains stable electrical performance under load. Engineered for durability, this HVAC motor run capacitor meets rigorous industry standards for safety, including a physical interrupter to prevent casing rupture during end-of-life failure. It effectively replaces common OEM parts from Genteq, GE, JARD, and Supco, making it a staple for any service truck inventory. Key Benefits for Contractors: Dual-Value Versatility: Handles both the 35 MFD compressor and 5 MFD fan motor requirements in a single, space-saving oval housing. High Voltage Endurance: Fully rated for 440V, allowing for safer operation and reduced stock by substituting for lower-rated 370V capacitors. Universal Compatibility: Direct replacement for Genteq C3355L, MARS 12185, and JARD 12885, ensuring quick uptime for client systems. Enhanced Safety: Includes a built-in pressure-sensitive interrupter (PSI) to protect the system electronics in the event of an internal short. Common Questions & Technical Support: Can I use a 440V run capacitor if the old one was 370V? Yes. In HVAC systems, you can always increase the voltage rating of a capacitor, but you must never decrease it. The MARS 12885 440V rating provides a more robust insulation barrier than 370V alternatives. What happens if I install the wrong MFD value? Using a value other than 35/5 MFD can cause the motor windings to overheat or fail to start. Always match the microfarad rating specified by the compressor or fan motor manufacturer. Does the orientation of the oval capacitor matter during installation? Unlike some electrical components, an oval run capacitor can be mounted in any orientation, provided it is secured with a mounting strap and the terminals are protected from contact with the cabinet.
