Key Features
- OEM-Rated Electrical Specification — Built to Husqvarna's exact voltage and current-switching ratings for this contactor position, ensuring the control circuit operates as engineered.
- Direct Panel Replacement — Matches the original mounting configuration and terminal layout, allowing a straightforward swap into the machine's electrical enclosure.
- Broad Floor Grinder Compatibility — Fits a wide range of Husqvarna PG-series and Duratiq/HTC floor grinders, including the PG690, PG830, DuratiqT5, DuratiqT8, DuratiqX8, and HTCT5, among others.
- Restored Motor Control — A fully functioning contactor switches motor current cleanly and reliably; a worn or failed unit causes erratic starting, motor drop-out, or a complete loss of drive power to the grinding heads.
- Electrical Safety Compliance — Using a genuine OEM contactor maintains the integrity of the machine's electrical control system and avoids the risk of undersized or mismatched switching components causing heat buildup or fault conditions.
A contactor is a heavy-duty electrically operated switch that controls power delivery to the grinder's drive motor or motors. When the operator initiates a start command, the contactor closes its contacts to complete the high-current circuit, allowing the motor to run; when the machine is stopped or a fault is detected, the contactor opens and interrupts that circuit instantly. A contactor that has worn contacts, coil failure, or welded contacts will cause the machine to fail to start, run intermittently, or — in the case of welded contacts — fail to shut down correctly, creating a serious safety risk.
