# US Seal BC-108 Motor Start Capacitor 108–130 MFD 250V

### 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
