MARS 12917 Run Capacitor

The MARS 12917 is a trade-grade 30 Microfarad 370Vac Oval Run Capacitor engineered for demanding HVACR motor applications. Designed as a high-reliability solution for residential and light commercial equipment, this 30 MFD run capacitor provides the necessary phase shift to optimize motor torque and efficiency in air conditioning units, heat pumps, and refrigeration compressors. The MARS 12917 features an oval aluminum case that facilitates easy mounting in tight electrical cabinets where space is at a premium.

As a veteran-preferred component in the HVAC capacitor replacement market, this unit is built with a pressure sensitive interrupter (PSI) to safely disconnect the capacitor in the event of an internal failure, preventing casing rupture. It is rated for continuous operation in environments ranging from -40°C to 70°C, meeting stringent EIA-456-A standards and UL/CSA safety requirements. This HVAC motor run capacitor is a non-PCB, environmentally safe alternative that serves as a direct universal replacement for many OEM 370V oval configurations, ensuring your equipment returns to peak electrical performance without unnecessary downtime.

• Enhanced Motor Efficiency: High-grade metallized polypropylene film dielectric ensures stable capacitance for 30 uF 370V oval requirements.
• Safe Failure Mode: Internal physical interrupter provides essential safety by preventing pressure-related ruptures.
• Broad Compatibility: Replaces common industry part numbers including JARD 12917, GE 97F9491, and CPT00202.
• Reliable Terminals: Equipped with standard 1/4-inch male quick-connect terminals for fast field installation.
• Heavy-Duty Construction: The aluminum housing offers superior heat dissipation and environmental Protection for long-cycle duty.

• Can I use a 440V capacitor to replace this 370V unit? Yes, a higher voltage rating (like 440Vac) can safely replace a 370Vac unit as long as the 30 MFD capacitance matches exactly.
• What does the "Oval" shape signify for installation? The oval geometry is a specific form factor; ensure your existing mounting strap or bracket is designed for an oval footprint rather than a round one.
• Is this capacitor suitable for 50Hz and 60Hz systems? Yes, the MARS 12917 is rated for both 50Hz and 60Hz frequencies, making it a versatile choice for various global power standards.
