MARS 11961 Start Capacitor
For high-demand motor starting applications, the MARS 11961 Start Capacitor provides the necessary torque to initiate heavy-duty compressor and motor loads. This 72-88 Microfarad 330Vac Round Start Capacitor is engineered as a dry electrolytic component, housed in a rugged, non-conductive phenolic case that resists oil, moisture, and debris in harsh mechanical environments. As a veteran-grade HVAC replacement part, it is rated for up to 20 starts per hour, ensuring reliable performance in residential and light commercial systems. The compact round design features dual 1/4-inch quick-connect terminals, maintaining compatibility across multiple brands including JARD, Packard, and DiversiTech. Designed to operate within a temperature range of -40°C to +65°C (-40°F to 149°F), this motor start capacitor is the standard choice for technicians seeking a 330 volt electrolytic capacitor that meets strict UL and CSA safety standards while effectively managing the high inrush current required for rapid motor acceleration.
Key Benefits:
- Universal Compatibility: Serves as a direct cross-reference for most 72-88 MFD 330V round start capacitors used in HVACR systems.
- Durable Construction: The hermetically sealed Bakelite case protects internal electrolytic elements from environmental contaminants.
- Optimized Torque: Specifically designed to provide a high-capacitance "kick," allowing AC compressors and motors to reach operating speed quickly.
- Standardized Terminals: Equipped with 1/4" male quick-connect tabs for fast, secure field installation without specialty tools.
Common Questions:
Can I use a capacitor with a higher voltage rating?
Yes, in motor applications, you can use a capacitor with a higher voltage rating (e.g., 330V to replace a 250V), but never use one with a lower voltage rating than the original specification.
Does the physical size of the capacitor matter?
While the MFD and voltage ratings are the critical electrical specifications, the physical dimensions must fit within the existing mounting bracket or motor shell for a secure installation.
When should a start capacitor be replaced?
Replacement is necessary if the motor fails to start but hums, if the capacitor shows visible signs of bulging or leaking, or if an MFD test shows a reading below the 72-88 microfarad range.
