MARS 12941 Run Capacitor
The MARS 12941 Run Capacitor is a high-performance 30 Microfarad 440Vac Oval Run Capacitor designed for continuous duty in demanding HVACR applications. Engineered for reliability, this single-section component features a metallized polypropylene film dielectric, ensuring low energy loss and consistent capacitance 30 MFD stability under varying thermal loads. As a veteran-grade OEM replacement capacitor, it operates at a 440 volt AC rating, making it backward compatible with 370V systems while providing superior dielectric strength to handle voltage spikes. The JARD 12941 series is oil-filled for optimal heat dissipation and includes an internal pressure-sensitive interrupter for safe end-of-life circuit disconnection. With a compact oval motor run capacitor form factor and 1/4-inch quick-connect terminals, it fits standard service brackets, making it a reliable choice for blower motors and compressor circuits in residential and light commercial units.
Key Benefits- High Dielectric Strength: Rated for 440Vac, offering a robust safety margin over standard 370V capacitors.
- Universal Application: Perfect for HVAC motor repair and compatible with widespread furnace, air handler, and condenser brands.
- Environmental Resilience: Operational temperature range from -40°C to 70°C, suitable for extreme outdoor environments.
- Safety Compliance: Features a 10,000 AFC internal protector and is UL/CSA recognized for professional installations.
- Energy Efficient: Low dissipation factor ensures maximum motor efficiency and reduced heat generation during operation.
Can I use a 440V capacitor if my original was 370V?
Yes. You can always increase the voltage rating (e.g., replacing a 370V with a 440V), as this provides a higher insulation breakdown point. However, you must never install a capacitor with a lower voltage rating than the original.
How do I determine if the 30 MFD rating is correct?
Always match the Microfarad (MFD or µF) rating exactly to the motor’s nameplate specifications. Using an incorrect capacitance can lead to excessive motor heat, reduced starting torque, and premature winding failure.
Does the oval shape affect performance versus a round capacitor?
No. The shape is strictly internal and for mounting clearance. If the MARS 12941 fits your bracket and provides 30 MFD at 440V, it will perform identically to a round equivalent.
