Key Features
- OEM Electrical Specification — manufactured to Husqvarna's exact coil voltage and contact rating, so the relay switches current at the correct threshold for the HTC80 series control system.
- Drop-In Connector Fit — this relay plugs directly into the existing harness socket with no rewiring or adaptation, restoring the circuit to its original configuration.
- Broad HTC80 Series Coverage — compatible with the HTC80, HTC80iD floor grinder, and HTCD80, covering the core machines in this floor grinding and dust management lineup.
- Restored Electrical Control — a failed relay can prevent the machine from starting, cause erratic motor behavior, or disable safety interlocks; replacing it with this genuine part restores normal electrical operation.
- Electrical Safety Compliance — using an OEM relay with the correct switching and insulation ratings keeps the machine operating within Husqvarna's designed electrical safety parameters.
A relay is an electrically operated switch that allows a low-current control signal to open or close a higher-current circuit within the machine. In floor grinders and associated dust equipment, relays are used to control motor start circuits, safety interlocks, and auxiliary functions. When a relay fails — whether through contact wear, coil burnout, or corrosion — the circuit it governs stops responding, which can result in a machine that won't start, runs intermittently, or loses a critical function entirely. Replacing the faulty relay restores proper electrical control and returns the machine to safe, reliable operation.
