MARS 12897 Run Capacitor
The MARS 12897 Run Capacitor is a high-performance 80/5 MFD 370V Dual Run Capacitor designed for continuous duty in residential and commercial HVAC units. Engineered to stabilize motor torque and current, this round dual run capacitor simultaneously supports the hermetic compressor and the condenser fan motor. Featuring a 370 VAC rating and a frequency range of 50/60 Hz, this 80/5 microfarad capacitor ensures consistent phase-shifted electrical power, preventing common multi-speed motor failures and maintaining air handler efficiency. Built to exceed EIA-456A industry standards, the 12897 is a critical HVAC replacement part for technicians requiring an OEM grade solution with a 60,000-hour operational life. Its aluminum housing and internal physical interrupter provide a reliable safety mechanism against internal pressure buildup, making it an ideal choice for high-draw condenser applications where reliability is non-negotiable.
Key Benefits for Contractors- Dual Capacitance Design: Integrates 80 MFD and 5 MFD ratings into a single round run capacitor to save space in the electrical compartment.
- Enhanced Safety: Equipped with a physical pressure-sensitive interrupter and non-PCB oil for secure operation in extreme temperatures (-40°C to +70°C).
- Broad Compatibility: Serves as a direct replacement for many standard 370V dual section capacitors in high-tonnage AC and heat pump units.
- Rugged Construction: Encased in a rust-resistant aluminum shell with standard 1/4-inch quick-connect terminals for fast field installation.
Can I use a 440V capacitor to replace this 370V model?
Yes, technicians can substitute a 440VAC capacitor for a 370VAC unit if the microfarad (MFD) rating is an exact match. However, never undersize the voltage by replacing a 440V unit with this 370V model.
What are the terminal designations on the 12897?
This capacitor uses standard designations: "C" for Common, "HERM" for the compressor (80 MFD), and "FAN" for the condenser fan (5 MFD).
How do I know if this capacitor needs replacement?
Look for physical signs such as a bulging top or leaking oil. Electrically, if the measured capacitance swings more than 5% outside the 80/5 rating, the component should be replaced to prevent motor overheating.
