MARS 12760 Run Capacitor

As a technician, you know that keeping a service truck stocked with the right dual run capacitor is the difference between an immediate fix and a second trip. The MARS 12760 is a trade-standard 20/5 MFD dual run capacitor designed for consistent motor and compressor performance in residential HVAC systems. Built to handle 370 VAC applications, this round dual run capacitor features a compact metal case and oil-filled construction for effective heat dissipation during continuous duty cycles. It serves as a reliable 20/5 microfarad capacitor replacement for condenser fan motors and compressors that require a combined 20+5 capacitance rating.

This HVAC run capacitor is engineered for precision, maintaining a strict tolerance to ensure your motors start and run within their specified amperage draws, preventing premature winding failure. The MARS 12760 features a patented pressure sensitive interrupter (PSI) that safely disconnects the capacitor if internal pressure builds up, protecting both the technician and the equipment. With standard 1/4-inch quick-disconnect terminals, this dual motor capacitor integrates seamlessly into existing wiring configurations for high-efficiency cooling systems.

• Dual Section Output: Provides 20 MFD for the compressor (HERM) and 5 MFD for the fan motor in a single, space-saving round profile.
• High Thermal Stability: Operates efficiently in temperatures ranging from -40°C to 70°C, typical of harsh outdoor condenser environments.
• Standardized Fit: The 3.74-inch height and approximately 2-inch diameter ensure compatibility with standard mounting straps.
• Safety Integrated: Internal physical interrupter provides protection against internal faults or casing ruptures.
• Environmental Compliance: Fully Non-PCB and technically rated for 50/60Hz operations.

• Can I use a 440V capacitor to replace this 370V model? Yes, technicians frequently use 440VAC capacitors as a heavy-duty substitute for 370VAC units, as long as the 20/5 MFD rating remains identical.
• Are the terminals interchangeable? Always follow the C (Common), FAN, and HERM (Compressor) markings on the top of the capacitor to ensure the correct circuit is provided with the appropriate capacitance.
• Does the physical shape matter? While shape doesn't affect electrical performance, this round dual capacitor is designed for circular mounting brackets; ensure your cabinet has the clearance for a round housing if replacing an oval unit.
