Copeland 914-0058-43 Start Capacitor

The Copeland 914-0058-43 Start Capacitor is a high-torque electrical component engineered for demanding HVACR applications, specifically for single-phase refrigeration compressors. Providing a capacitance range of 243-292 MFD with a 250V voltage rating, this dry, electrolytic capacitor is designed for intermittent duty to significantly increase motor starting torque. It features a robust phenolic resin housing that is moisture and oil resistant, ensuring long-term durability in high-vibration environments. This specific model is a direct fit for the Copeland RRT64C1E-IFA-959 and is frequently paired with a 032-0359-00 capacitor clamp. Technicians should note that these AC motor starting capacitors include a pre-soldered bleed resistor to prevent erratic relay operation and contact welding by quickly depleting the electrical charge after start-up. For a successful install, verify your potential relay condition to prevent overheating or premature failure of the 243-292 uF capacitor during the initial quarter-second of cycle engagement.

• High Torque Starting: Engineered for systems requiring 243-292 microfarads to overcome high head pressure during startup.
• Bleed Resistor Integrated: Prevents sticking relay contacts and arcing by rapidly discharging the 250V start capacitor.
• Industrial Durability: Housed in a moisture-resistant phenolic resin case to withstand harsh mechanical room conditions.
• OEM Compatibility: Genuine Copeland compressor parts ensure precise capacitance matching for motor start windings.

• Can I use this for both 110V and 220V systems? Yes, this 250V rated capacitor is suitable for 115V or 230V circuits, provided the original part specs fall within the 243-292 MFD range.
• Why did my previous capacitor blow its top? Typically, this is due to a failed potential relay or thermistor that stayed closed too long, causing the capacitor to overheat.
• Does this include the mounting clamp? This unit is often sold as a kit (914-0058-43) which generally includes the compatible mounting bracket.
