Packard PRMJ72 Start Capacitor

When you're dealing with a compressor or motor that's struggling to roll over, the 72-88 MFD 330V Start Capacitor is the reliable standby for heavy-duty starting torque. Built for intermittent AC duty, this moisture and oil-resistant Packard PRMJ72 features a round phenolic case—industry standard for heat dissipation and durability in tough mechanical rooms. This is a non-polarized, dry electrolytic component designed specifically to provide the necessary phase shift to get equipment up to 75% of rated speed before the centrifugal switch or relay kicks it out of the circuit.

Replacing a weak or bulged unit with this 330 VAC motor start capacitor ensures your service call doesn't result in a callback. It features dual 1/4-inch male blade terminals for quick integration. With an operating range of -40°F to 149°F, this 72-88 microfarad capacitor maintains performance in unconditioned spaces or high-heat environments. Verify your voltage; while a 330V unit can replace a lower-rated 125V or 250V capacitor of the same MFD, never downsize the voltage rating.

• High-torque starting power for HVAC compressor motors and pump applications.
• Rugged round start capacitor design encased in moisture-proof phenolic resin.
• Standardized dual blade terminals for universal wiring compatibility.
• Engineered for intermittent duty motor starting with rapid discharge capability.
• UL and cUL recognized for safety in commercial and residential installations.

• Can I use a higher voltage capacitor? Yes, the 330V rating is a maximum threshold. You can safely use this heavy duty start capacitor to replace units rated at 110V, 125V, or 250V as long as the 72-88 MFD range matches.
• Why is my start capacitor leaking fluid or bulging? These electrolytic units are for "start only." If the start relay fails to disconnect the capacitor, it will overheat and fail. Always check the potential relay during replacement.
• What happens if the capacitance (MFD) is too low? If you use a lower MFD than the OEM spec, the motor may not generate enough torque to break friction, leading to a locked rotor condition.
