LEESON 003049.04 Start Capacitor
The LEESON 003049.04 Start Capacitor is a heavy-duty motor start capacitor engineered for high-torque applications in single-phase electric motors. Operating at 250VAC with a capacitance range of 351–430 MFD, this Regal Rexnord component is essential for initiating the high-starting torque necessary to overcome mechanical loads in industrial and commercial gear. Designed with a round phenolic case, it measures approximately 2-9/16 inches in diameter and 4-3/8 inches in height, ensuring a standard fit for most OEM capacitor housing configurations. This model includes an integrated 15k-ohm bleeder resistor, which is critical for discharging stored energy between cycles to protect start-switch contacts and solid-state relays from premature arcing and failure.
Key Benefits
- High-Capacitance Performance: Provides a robust 351–430 microfarad range to ensure consistent motor rotation under heavy start loads.
- Bleeder Resistor Integration: Features a factory-installed 15k-ohm resistor to mitigate voltage spikes and extend the lifespan of internal switching components.
- Industrial-Grade Build: Constructed with a durable round phenolic resin body, rated for operating temperatures up to +65°C.
- Universal Terminal Connection: Equipped with dual 1/4-inch quick-connect spade terminals for fast, secure field installation.
- Broad Compatibility: A direct OEM replacement start capacitor for various Leeson and Marathon motors used in fans, pumps, and compressors.
Common Questions
Is the bleeder resistor required for the LEESON 003049.04?
Yes, for most high-cycle industrial motors, the bleeder resistor is vital. It facilitates the safe discharge of voltage after the start circuit opens, preventing damage to the starting switch or relay.
Can I use this to replace a capacitor with a slightly lower MFD range?
While minor variations in capacitance can sometimes be tolerated, it is highly recommended to match the 351–430 MFD and 250VAC specs to ensure your motor develops the proper starting torque without overheating the windings.
How do I confirm the fitment for my motor housing?
The LEESON 003049.04 is a standard Round Case (Type 1) design. Technical specs indicate dimensions of roughly 2.56" x 4.38"; always measure your existing capacitor's cavity before ordering.
