Single Run Capacitor, Round, 10/440 uF

Consistent HVAC Motor Support – Mars 12732 Jard 10 µF 440V Round Run Capacitor

The Mars 12732 Jard Run Capacitor is a single-value component rated for 10 microfarads at 440 volts AC, designed for continuous-duty operation in HVAC motor circuits. Engineered for long-term reliability, it features a round metal case and meets standard specifications required in professional HVAC applications.

Applications and Use Cases

This capacitor is suited for use in fan motors, blower assemblies, and condenser units where a single-run capacitor is specified. Its 440V rating ensures overhead tolerance, making it appropriate for use in environments with voltage fluctuation or high ambient temperature.

Technical Characteristics

• Capacitance: 10 µF
• Voltage Rating: 440 VAC
• Case Shape: Round
• Frequency: 50/60 Hz
• Temperature Range: -40°C to +70°C
• Construction: Non-PCB, self-healing dielectric
• Interrupter: Integrated pressure-sensitive safety switch

Installation Guidance

Installation is straightforward for a licensed HVAC technician. The capacitor is designed for horizontal or vertical mounting and should be secured using standard brackets. Always verify microfarad and voltage requirements against system specifications and discharge the previous capacitor before removal to prevent arc flash.

Highlights for Field Technicians

• ✅ Field-Proven Durability – Rugged aluminum housing withstands mechanical and thermal stress.
• ✅ Safe Operation – Meets UL 810 with internal pressure interrupter for fault protection.
• ✅ Direct Replacement – Compatible with many OEM part numbers requiring 10 µF at 440V in round format.

Note

Always verify that the replacement capacitor matches the original component’s µF and voltage ratings. Substituting with an incorrect part may compromise system performance or lead to premature failure.
