Key Features
- OEM-Matched Switching Specification — Built to Husqvarna's original electrical ratings, so current load, coil voltage, and contact configuration align precisely with your grinder's control system.
- Direct-Swap Replacement — Mounts to the existing electrical housing using the original connection points, allowing a straightforward swap without rewiring or adapting terminals.
- Confirmed Compatibility — Engineered to fit the PG680 and PG820 planetary floor grinders, covering both machines in a single genuine OEM part.
- Restored Motor Control Performance — A functioning contactor reliably engages and disengages the drive motor on command; a failed contactor can prevent the machine from starting or cause uncontrolled operation.
- Electrical Safety Integrity — Using a genuine OEM contactor maintains the designed overcurrent protection behavior built into the grinder's electrical circuit, an important consideration for operator safety on powered floor equipment.
A contactor is an electrically controlled switch that opens and closes the high-current circuit powering the grinder's drive motor. When the operator activates the machine, the control circuit energizes the contactor's coil, which pulls the contacts closed and allows current to flow to the motor. When the contactor wears out or fails, the motor may refuse to start, cut out unexpectedly during operation, or fail to stop when commanded — any of which disrupts productivity and can create a safety concern. Replacing a faulty contactor with a genuine Husqvarna part restores the correct electrical switching behavior the PG680 and PG820 were designed to deliver.
