The Husqvarna PG 280 Electronic Box 5871739-01 is a replacement electrical component for compatible 230V 50Hz single-phase Husqvarna PG 280 floor grinders.
Also identified by the continuous part number 587173901, this electronic box forms part of the PG 280 electrical system and is specifically listed for the 1-phase, 230V, 50Hz machine configuration.
This makes it particularly relevant when repairing compatible Australian-specification PG 280 floor grinders operating from a single-phase 230V power supply.
The electronic box is located within the machine's electrical assembly alongside components including the motor capacitors, centrifugal switch, contactor, relay and associated wiring.
When diagnosing an electrical or motor-starting problem on a PG 280, the complete electrical system should be inspected before replacing individual components. Capacitors, switches, wiring, connections and other electrical components can produce similar symptoms when faulty.
Part number 5871739-01 is the single-phase version. It should not be confused with 5871739-02 / 587173902, which is listed as the three-phase electronic box.
The same 587173901 electronic box also appears in selected Husqvarna PG-series floor grinder parts documentation. Always confirm the machine model, voltage, frequency, phase and required part number before ordering.
