MARS 12119 Run Capacitor

Professional-grade MARS 12119 Run Capacitor units provide reliable phase-shift correction for dual-motor HVACR circuits. Specifically engineered as a 35/6 Microfarad 440Vac Round Dual Run Capacitor, this component features a split-capacitance design to manage both the HVAC compressor and the condenser fan motor simultaneously. Built to EIA-456-A standards, the aluminum-cased, oil-filled dielectric ensures stable thermal dissipation in high-ambient environments. Verified as UL recognized and CSA certified, the internal pressure-sensitive interrupter acts as a critical safety circuit, disconnecting the capacitor under internal fault conditions to prevent case rupture. The 440V dual run capacitor is rated for 50/60 Hz and serves as a direct OEM replacement capacitor for multiple Carrier, Bryant, and Payne units. As a veteran-preferred MARS Blue Box part, it utilizes 1/4-inch quick-connect terminals labeled C, HERM, and FAN for error-free wiring during field service.

• Dual-Circuit Support: Manages current for both the compressor (35 MFD) and fan motor (6 MFD) within a single round footprint.
• Enhanced Voltage Rating: The 440Vac rating allows this unit to replace 370V capacitors, providing a higher safety margin against line voltage fluctuations.
• Industrial Construction: Non-PCB, oil-filled aluminum housing designed for longevity in extreme service temperatures from -40°C to +70°C.
• Safety Compliance: Features an integrated physical interrupter and meets rigorous UL listed safety benchmarks for electrical components.
• Compact Profile: Dimensions are optimized for standard HVCAR equipment mounting straps and tight control box tolerances.

Can I use a 440V capacitor if my old one was 370V?
Yes. While you must match the MFD rating exactly (35/6), a higher voltage rating like 440V is an acceptable and often preferred upgrade over a 370V unit as it withstands more electrical stress.

What do the C, HERM, and FAN terminals signify?
The "C" terminal is the Common line, "HERM" connects to the hermetic compressor lead, and "FAN" connects to the condenser fan motor circuit. Always discharge the old capacitor before handling.

Does this capacitor work with both 50Hz and 60Hz systems?
This 35/6 MFD capacitor is rated for both 50Hz and 60Hz frequency applications, making it suitable for a wide range of domestic and international HVAC hardware.
