LEESON 003049.11 Start Capacitor
The LEESON 003049.11 Start Capacitor is a high-performance 351-430 MFD start capacitor engineered for demanding single-phase motor applications. Designed for intermittent duty, this 330VAC motor start capacitor provides the necessary phase shift to generate the high starting torque required to overcome mechanical inertia. Encased in a rugged, moisture-resistant round phenolic case, it is built to withstand standard HVACR environments. The unit features 1/4 inch spade terminals for secure electrical connections and an integrated 15K Ohm resistor to bleed off residual voltage, protecting sensitive downstream components. This capacitor is a precise OEM replacement capacitor for LEESON and Marathon motors, ensuring direct compatibility and maintaining factory performance specifications. With a diameter of 2.56 inches and a height of 4.38 inches, it fits standard mounting brackets. Technicians should verify that the microfarad range and voltage rating align with the motor nameplate to prevent winding stress and ensure reliable equipment cycling.
Key Benefits
- Universal 351-430 uF capacitance range provides robust starting torque for heavy-load compressors and fan motors.
- High 330V AC rating offers an increased safety margin over standard 110V or 250V start capacitors.
- Integrated discharge resistor ensures safe handling and prevents arcing across start relay contacts.
- Durable phenolic resin housing protects internal electrolytic elements from oil, moisture, and debris.
- Standard dual male quick-connect terminals facilitate rapid field replacement and reduced downtime.
Common Questions
Can I use a higher MFD start capacitor than the original?
While a slightly higher microfarad rating (up to 20%) can improve starting torque, it must be matched to the motor’s specific design to avoid damaging the start windings or the centrifugal switch. Stick to the 351-430MFD range if specified by the manufacturer.
How do I know if my start capacitor has failed?
Visual indicators include a bulging top, leaking fluid, or a blown pressure relief plug. Electrically, a failed capacitor often results in a humming motor that fails to rotate or trips the circuit breaker immediately upon startup.
Is this capacitor compatible with 115V or 230V systems?
Yes, the 330VAC rating is a maximum threshold. This capacitor is fully compatible with motors operating at 110V, 125V, 220V, or 250V, provided the MFD range matches the application requirements.
