Industrial 540-648 Start Capacitor 110 125V AC

Rotom Industrial 540-648 Start Capacitor, 110/125V AC, is a dry electrolytic, non-polarized motor-start capacitor rated for 540–648 MFD. It is designed for capacitor-start or capacitor-start/run single-phase motors and provides the start-up phase shift needed to initiate motor rotation. Operated on 50/60 Hz power, this round capacitor is built for intermittent starting duty in motor circuits and is commonly used in HVAC equipment such as condenser fans, blower motors, compressors, and pumps that require a high start-capacitance during startup. In Rotom’s lineup, it is frequently cataloged with 540–648 MFD and 110/125V specifications, and cross-referenced part numbers such as 35-540D125. This combination of capacitance and voltage makes it suitable for a wide range of motors that specify 110–125V and a 540–648 MFD rating, delivering reliable starting torque in industrial and commercial applications.
