MARS 12245 Run Capacitor
The MARS 12245 Run Capacitor is a high-performance 40 MFD 440V round run capacitor engineered for demanding HVACR applications. Designed for single-phase motor support, this 40 microfarad capacitor ensures consistent phase shift for optimal torque and compressor efficiency. As a veteran-preferred HVAC replacement part, it features a dual-voltage rating of 440/370 VAC, allowing it to handle higher thermal loads while remaining backwards compatible with 370V systems. The durable aluminum casing contains non-PCB oil and incorporates a built-in physical interrupter to protect the condenser fan motor or compressor during internal pressure buildup. This MARS 12245 unit meets EIA-456-A standards, offering a 60,000-hour operational life. With a compact 3.75-inch can height, it fits standard mounting brackets, making it a reliable 440 volt round capacitor for routine service calls and motor maintenance.
Key Benefits:- High Reliability: Rated for 60,000 hours of operational life, meeting strict EIA-456-A performance standards.
- Universal Compatibility: 440/370 VAC dual voltage rating permits use in both high and standard voltage applications.
- Safety Engineered: Features an internal pressure interrupter and non-PCB construction for secure field operation.
- Compact Form Factor: Round aluminum housing designed for easy installation in tight electrical service panels.
- Can I use this 440V capacitor to replace a 370V unit? Yes, a higher voltage rating is a safer substitute for a lower voltage rating as long as the 40 MFD capacitance matches precisely.
- Is this capacitor compatible with 50Hz systems? Yes, the MARS 12245 is rated for both 50Hz and 60Hz frequencies, suitable for international equipment.
- How do I verify the capacitance is still within spec? Use a multimeter with a capacitance setting; the rating should remain within +/- 6% of 40 microfarads for proper motor performance.
