MARS 12007 Run Capacitor

The MARS 12007 is a trade-grade 7.5 MFD 370V oval run capacitor engineered for high-duty cycle performance in residential and light commercial HVACR equipment. This single capacitance unit is a standard OEM replacement part for fan motors and compressors, effectively stabilizing the phase shift required for motor torque. Built with a durable aluminum case and non-PCB oil, it integrates a pressure-sensitive interrupter to safely disconnect the circuit in the event of internal failure or excessive pressure buildup.

Designed for versatile field use, the MARS 12007 features a 50/60 Hz frequency rating and is tested to meet EIA-456-A standards for up to 60,000 hours of operational life. Its compact oval profile allows for seamless installation in tight control boxes where space is at a premium. Technicians can confidently use this capacitor as a universal motor run capacitor replacement for various P291 and various Genteq or Aerovox equivalents, provided the 7.5 microfarad and 370 VAC ratings are matched or exceeded by voltage.

• High-Reliability Safety: Features a built-in physical interrupter to prevent case rupture under fault conditions.
• Universal Compatibility: Replaces standard 7.5 microfarad 370V oval capacitors from major brands like Carrier, Rheem, and Trane.
• Long Service Life: Industrial-grade construction designed for 60,000 hours of reliable motor operation.
• Thermal Stability: Operates efficiently within a temperature range of -40°C to 70°C.

Can I use a 440V capacitor to replace this 370V MARS 12007?
Yes, you can use a capacitor with a higher voltage rating (like 440V) as long as the microfarad (7.5 MFD) rating is identical and the physical dimensions fit the mounting bracket.

What are the physical dimensions for mounting?
The MARS 12007 typically measures approximately 2-3/8 inches in case height and 2-1/16 inches in width, though exact dimensions may vary slightly by production run; always verify the oval footprint against your original bracket.

Are these capacitors safe for environmentally sensitive sites?
Yes, this is a non-PCB, oil-filled capacitor, making it compliant with modern environmental safety regulations for residential and commercial disposal.
