Keep Pool & Spa Motors Running Smoothly and Efficiently

A motor run capacitor is essential for maintaining steady, efficient operation after a motor starts. The US Seal RD-25-370 Motor Run Capacitor is designed to support continuous operation in pool pumps, spa motors, and blowers by delivering stable electrical capacitance throughout the motor’s run cycle. Rated at 25 MFD and 370VAC, this OEM-grade capacitor helps motors run cooler, quieter, and more efficiently.

When a run capacitor weakens or fails, motors may overheat, lose efficiency, or shut down unexpectedly. Replacing it with the correct capacitor protects your equipment and helps prevent premature motor failure.

Engineered for Pool & Spa Motor Duty Cycles

Pool and spa motors often operate for extended periods in warm, demanding environments. The US Seal RD-25-370 motor run capacitor is built specifically for these conditions, offering consistent electrical performance and moisture-resistant construction suitable for outdoor pool equipment.

This capacitor is commonly used in single-phase pool pump motors, spa motors, and blowers that require a 25 MFD run capacitor rated at 370VAC.

Why the Correct Run Capacitor Matters

Motor run capacitors directly affect how efficiently a motor operates during normal use. An incorrect or failing capacitor can increase electrical draw, reduce flow, and shorten motor life.

Why it matters:

• Helps motors run cooler and more efficiently

• Reduces electrical stress during extended run times

• Prevents unexpected shutdowns and overheating

• Extends the service life of pool and spa motors
