Mars 12229 Run Capacitor 70 Mfd 370V

Product Description

The MARS 12229 is a run capacitor rated at 70 MFD and 370 volts, designed for use in single-phase AC motors found in HVAC equipment. MARS, short for Motors and Armatures, is a trusted name in the HVAC and refrigeration industry, supplying technicians with reliable motor components and electrical parts. This run capacitor provides the continuous phase shift needed to keep a motor running smoothly after startup. Without a functioning run capacitor, the motor draws excess current, runs hot, and eventually fails. Replacing a worn or failed run capacitor with the correct MFD and voltage rating restores proper motor operation quickly and cost-effectively. The 12229 is rated at 70 MFD, which is a higher capacitance value suited for larger single-phase motors such as those found in commercial HVAC condensers, large air handlers, and industrial refrigeration compressors. The 370-volt rating means it is compatible with standard 208 to 240-volt single-phase motor circuits. Run capacitors with a 370-volt rating can also be used in circuits where a 440-volt capacitor would normally be specified, as long as the MFD value matches. HVAC technicians rely on run capacitors like the MARS 12229 as a go-to replacement part for condenser fan motors, blower motors, and compressor start circuits. Keeping this capacitor on a service vehicle ensures fast, accurate repairs in the field. The cylindrical metal case is standard for round run capacitors and fits most common capacitor brackets and mounting hardware. This is a direct replacement option for any motor application requiring a 70 MFD, 370-volt run capacitor.
