MARS 12076 Run Capacitor

The MARS 12076 is a professional-grade 60/3 MFD 370V dual run capacitor designed for high-performance HVACR applications. Engineered as an OEM replacement capacitor, this round aluminum-cased component provides simultaneous support for both the compressor and condenser fan motor, ensuring stable phase-shift and torque during startup and continuous operation. With a capacitance rating of 60+3 microfarads (uF) and a 370VAC voltage ceiling, it is built to withstand the rigorous thermal demands of modern residential and commercial air conditioning systems. The MARS 12076 features a physical internal interrupter for safety and is rated for an operational life of approximately 60,000 hours under standard conditions. As a non-PCB, round dual run capacitor, it meets the EIA-456-A test standards, making it a reliable solution for technicians troubleshooting humming compressors, slow-starting fans, or failed capacitors in the field. Its compact geometry and standard 1/4-inch terminals allow for efficient retrofitting in tight electrical cabinets.

• Dual-Section Versatility: Consolidates 60 MFD and 3 MFD capacitance into one footprint to drive both the hermetic compressor and fan motor.
• Industrial Durability: Rated for a wide temperature range of -40°C to +70°C, suitable for extreme outdoor condenser environments.
• Safety Compliance: Incorporates a physical pressure-sensitive interrupter and is UL and CSA listed for secure field integration.
• Extended Service Rail: Engineered for up to 60,000 hours of operational life, reducing the frequency of maintenance callbacks.
• Universal Compatibility: Standard 370VAC rating supports a broad spectrum of HVAC brands requiring 60+3 MFD specifications.

Can I use a 440V capacitor to replace this 370V model?
Yes, in modern HVACR practice, a higher voltage rating (440V) can safely replace a lower rating (370V) as long as the capacitance (60/3 MFD) remains identical. However, never undersize the voltage rating below the original OEM requirements.

What are the signs of a failed 60/3 MFD capacitor?
Technicians should look for physical bulging at the top of the can, oil leaks, or a compressor that hums but fails to engage. Use a multimeter to verify that the MFD readings are within the +/- 5% or 6% tolerance specified on the label.

How do I identify the terminals for wiring?
The MARS 12076 features industry-standard markings: 'C' for Common, 'HERM' for the compressor lead, and 'FAN' for the condenser fan lead. Always discharge the capacitor before handling wires.
