Key Features
- OEM Electrical Specification — Manufactured to Husqvarna's exact capacitance and voltage rating, ensuring the motor receives the correct starting surge without overload or underperformance.
- Direct Drop-In Replacement — Engineered to match the original mounting configuration and terminal connections on the PG400, allowing straightforward installation without modification.
- PG400 Floor Grinder Fitment — Verified for use with the Husqvarna PG400 planetary floor grinder, keeping your machine operating to its designed specification.
- Restored Motor Starting Performance — A failed or degraded capacitor causes sluggish or failed motor starts; replacing it with this genuine part restores immediate, full-power start-up on every cycle.
- Electrical Safety Compliance — Using the correct OEM-rated capacitor protects the motor windings from starting-current damage and reduces the risk of electrical faults associated with incorrect component substitution.
A capacitor in a floor grinder provides the phase shift needed to generate starting torque in the electric motor. Without a functioning capacitor, the motor may fail to start, start slowly, or draw excessive current that can damage the windings over time. When a capacitor degrades — which typically presents as humming without rotation, tripped breakers, or intermittent start failures — replacing it promptly with a correctly rated unit like this one restores normal operation and protects the motor from secondary damage.
