Run Capacitor, Oval, 2 MFD, 440/370

Jard Mars2 2 µF Oval Motor Run Capacitor – 440V, Continuous Duty

The Mars 12926 (Mars2 series) is a 2 µF motor run capacitor rated for 440 VAC, designed to provide continuous-duty support in single-phase induction motor applications. Commonly used in HVAC fan motors, blowers, and auxiliary components, this oval-style capacitor is engineered for reliable performance in high-cycle environments.

Manufactured with metallized polypropylene film and housed in a non-PCB aluminum case, the Mars2 12926 is compliant with industry standards for performance and safety. Its compact oval design allows for easy integration into systems with limited installation space, particularly where cylindrical profiles are not suitable.

Installation Notes

This capacitor is intended for installation by qualified HVAC technicians. Always disconnect power and discharge the existing capacitor before removal. Match both µF and voltage ratings to the motor’s original specifications. Mounting brackets should be used as required to secure the oval case within the cabinet or motor housing.

Use Case and Field Application

The 12926 is ideal for use in motors with low-capacitance requirements, typically found in air handler blowers, ventilation systems, or secondary fan circuits. Its compact form allows for integration into tight enclosures where standard round capacitors may not fit.

Contractor Benefits

• ✅ High Voltage Endurance: Rated for continuous duty at 440V for robust system compatibility.
• ✅ Compact Profile: Oval form factor supports installations in constrained spaces.
• ✅ Field-Tested Reliability: Built to withstand thermal cycling and vibration common in HVAC applications.
• ✅ Maintenance-Friendly: Standard terminal configuration simplifies diagnostic testing and replacement.
