US Seal Run Capacitor 5VR0303 – 30 MFD, 370VAC | PRC30M
Maintain Efficient, Stable Operation in Pool & Spa Motors
A properly functioning motor run capacitor is essential for keeping pool pumps and spa motors operating smoothly during extended run cycles. The US Seal Run Capacitor 5VR0303 (PRC30M) is designed to provide steady electrical support throughout motor operation, helping equipment run cooler, quieter, and more efficiently. Rated at 30 MFD and 370VAC, this OEM-compatible capacitor is a reliable replacement for worn or failing run capacitors in pool pumps, spa motors, and blowers.
When a run capacitor begins to degrade, motors may lose efficiency, overheat, or shut down unexpectedly. Replacing it with the correct capacitor helps protect your motor, reduce electrical strain, and extend equipment life.
Built for Continuous Pool & Spa Motor Duty
Unlike start capacitors, run capacitors remain engaged while the motor is operating. Pool and spa motors rely on them to maintain proper electrical balance during long run times. The US Seal 5VR0303 run capacitor is engineered specifically for these demands, with a sealed, durable design suited for outdoor pool equipment environments.
This capacitor is commonly used in single-phase pool pump motors, spa motors, and blowers requiring a 30 MFD run capacitor rated at 370VAC.
Why the Correct Run Capacitor Matters
Using the proper motor run capacitor directly affects motor efficiency and longevity. An incorrect or failing capacitor can increase electrical draw and shorten motor life.
Why it matters:
-
Helps motors run cooler and more efficiently
-
Reduces electrical stress during continuous operation
-
Prevents overheating and unexpected shutdowns
-
Extends the service life of pool and spa motors
