Faqs

What is Husqvarna part number 5871743-01?

Part number 5871743-01 / 587174301 is an electric centrifugal switch used in compatible Husqvarna floor grinders. It is identified as the WECS-240-75 switch.

Is 5871743-01 suitable for the Husqvarna PG 280?

Yes. Part number 5871743-01 is listed for compatible 230V 50Hz Husqvarna PG 280 floor grinders.

What voltage is the 5871743-01 centrifugal switch?

This version is specified for 230V, 50Hz applications. Different part numbers are used for other voltage and frequency configurations.

What does a centrifugal switch do in a single-phase motor?

A centrifugal switching system controls the motor's starting circuit. During start-up, the starting circuit helps the motor develop sufficient starting torque. Once the motor reaches the required operating speed, the centrifugal switching system changes the state of the starting circuit.

Can a faulty centrifugal switch cause a PG 280 not to start correctly?

A faulty centrifugal switch can be one possible cause of motor starting problems. The start capacitor, run capacitor, wiring and other electrical components should also be inspected when diagnosing a starting fault.

Does this switch fit the PG 450 and PG 510?

Part number 587174301 is also documented in selected Husqvarna PG 450 and PG 510 electrical assemblies. Always confirm the machine voltage, frequency and required part number before ordering.

Is 5871743-01 the same as 587174301?

Yes. 5871743-01 and 587174301 are different formatting styles for the same part number.

    The Husqvarna PG 280 Electric Centrifugal Switch 5871743-01 is a replacement electrical component for compatible 230V 50Hz Husqvarna PG 280 floor grinders. Also identified by the full part number 587174301, this component is listed as an Electric Centrifugal Switch and is identified as WECS-240-75 in parts documentation. The centrifugal switch forms part of the single-phase motor electrical system and works in conjunction with the motor's starting circuit. During motor start-up, the starting circuit provides the additional torque required to bring the motor up to operating speed. The centrifugal switching system then changes the state of the starting circuit once the motor reaches the required speed. A faulty centrifugal switch can contribute to motor starting problems and should be correctly diagnosed before replacement. Because the PG 280 starting system also incorporates start and run capacitors, these components should also be checked when troubleshooting motor starting issues. Part number 5871743-01 is specifically listed for 230V, 50Hz applications. Different switch versions are used for other voltage and frequency configurations, so the machine's electrical specification and existing part number should always be confirmed before ordering. The same 587174301 switch is also documented in selected Husqvarna PG 450 and PG 510 floor grinder electrical assemblies. Ideal for professional repair technicians, concrete grinding contractors and equipment owners carrying out maintenance or electrical repairs on compatible Husqvarna floor grinders.
