Key Features
- Correct Electrical Specification — Genuine OEM construction ensures this capacitor meets the exact capacitance and voltage rating required by the original motor circuit, delivering consistent start and run performance.
- Direct Drop-In Replacement — Engineered to match the original mounting configuration and terminal connections of the listed Husqvarna floor grinders, so installation is straightforward.
- Broad Floor Grinder Compatibility — Fits HTC280, HTC510, PG280, PG450, PG510I, PG510, and HTC450 floor grinders, covering a wide range of Husqvarna's professional grinding and surface prep lineup.
- Restored Motor Starting Power — A functioning capacitor provides the surge current needed to bring the grinder motor up to operating speed; a failed unit causes hard starts, motor humming, or failure to start entirely.
- Electrical Safety Compliance — Using the correct OEM-specified capacitor prevents overloading the motor windings and reduces the risk of overheating or tripped protection devices during operation.
A capacitor in a floor grinder serves a critical role in the motor's electrical circuit, storing and releasing the burst of energy needed to initiate motor rotation and maintain a stable run phase. Without a properly functioning capacitor, the motor may struggle to start, run erratically, or draw excessive current that can damage the windings over time. Replacing a failed capacitor with a genuine OEM unit like this one restores normal motor behavior and protects the broader electrical system of the grinder.
