US Seals BC-108 Motor Start Capacitor – 108–130 MFD, 250VAC
Restore Reliable Starts to Pool & Spa Motors
When a pool pump or spa motor fails to start properly, the issue is often a worn or failing motor start capacitor—not the motor itself. The US Seals BC-108 Motor Start Capacitor is designed to deliver the exact surge of electrical energy required to start single-phase pool pumps, spa motors, and blowers smoothly and efficiently. With a rating of 108–130 MFD at 250VAC, this OEM-grade replacement helps eliminate hard starts, humming motors, and intermittent startup failures.
Replacing a failing capacitor early protects your motor from excessive strain, overheating, and premature failure, making this a simple and cost-effective repair for both pool professionals and homeowners.
Designed Specifically for Pool & Spa Equipment
Pool and spa motors operate in demanding environments with frequent on/off cycles and exposure to heat and vibration. The US Seals BC-108 motor start capacitor is engineered specifically for these conditions, ensuring consistent performance and reliable startups across a wide range of pool equipment applications.
This capacitor is commonly used in single-phase pool pump motors, spa blowers, and other pool-related electric motors that require a high-capacity start capacitor to overcome initial load resistance.
Why the Correct Start Capacitor Matters
Using the correct MFD-rated motor start capacitor is critical for proper motor operation. An incorrect or failing capacitor can cause the motor to struggle, overheat, or fail entirely. The BC-108 delivers the correct capacitance range needed to bring motors up to speed quickly and safely.
Why it matters:
-
Reduces motor stress during startup
-
Helps prevent breaker trips and overheating
-
Extends the life of pool pump and spa motors
-
Restores proper torque and startup reliability
