The Husqvarna 587174405 Capacitor is a genuine OEM component designed for the HTC280 and HTC450 floor grinders. As a factory-sourced replacement, it is built to the exact electrical specifications Husqvarna requires for correct motor starting and sustained operation in these machines. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Correct Electrical Rating — Manufactured to the precise capacitance value specified by Husqvarna, ensuring proper motor start and run cycles without over- or under-loading the electrical system.
- Genuine OEM Component — Sourced directly from Husqvarna, this capacitor meets the same specifications as the original part installed at the factory — no guesswork on compatibility.
- Direct-Fit Replacement — Engineered to connect directly into the existing wiring configuration of the HTC280 and HTC450, allowing straightforward installation without modification to the electrical harness.
- Protects Motor Performance — A functioning capacitor delivers the start-up current surge the motor needs; a failed capacitor can prevent the grinder from starting or cause the motor to run hot and draw excessive current.
- Electrical Safety Compliance — Using the OEM-rated capacitor maintains the machine's original electrical safety margins, reducing the risk of nuisance tripping, overheating, or motor damage from an incorrectly rated component.
A capacitor in a floor grinder serves as an energy-storage component within the motor's electrical circuit, providing the burst of current needed to start the motor and helping to maintain a stable phase relationship during operation. Without a properly functioning capacitor, the motor may fail to start, run sluggishly, or draw more amperage than intended — leading to overheating and premature motor wear. Replacing a faulty capacitor with the correct OEM part restores normal starting behavior and protects the motor windings from the strain of repeated failed start attempts.
Always cross-reference part number 587174405 against your machine's parts diagram before ordering to confirm it matches your specific HTC280 or HTC450 configuration. For questions about fitment or ordering, contact the DHS Equipment team.
