The Wacker Neuson is a genuine OEM Centrifugal Switch designed for the PS3 2200, PS3 1500, PSW3 1500, and PS2-1500 series submersible pumps. As a factory-sourced component, it meets the exact electrical specifications required for proper motor startup and run performance in these Wacker Neuson PS-series units. This switch is a direct-fit replacement, matching the original mounting configuration and wiring connections inside the pump motor housing. If your pump is failing to start, running continuously without cycling, or tripping on overload, the centrifugal switch is a common service point and this part restores correct operation.
Key Features
- Correct Switching Threshold: — Sourced directly from Wacker Neuson, this centrifugal switch is calibrated to the precise RPM engagement point required by the PS-series motor — not a generic approximation.
- Drop-In Motor Fit: — Matches the original internal mounting points and terminal connections inside the pump motor, allowing straightforward installation without reworking the motor assembly.
- Broad PS-Series Coverage: — Compatible with PS3 2200, PS3 1500, PSW3 1500, and PS2-1500 submersible pump models, making it a practical stocking part for fleets running multiple Wacker Neuson PS units.
- Restores Clean Motor Startup: — A failed centrifugal switch causes hard starts, motor humming, or failure to disengage the start winding — replacing it brings the motor back to correct two-winding operation and protects the motor windings from overload.
- Electrical Safety Compliance: — Using the genuine OEM switch ensures the start-winding cutout occurs at the correct speed, preventing sustained current draw that can damage motor windings or trip thermal protection in submersible applications.
A centrifugal switch is an electromechanical component located inside the motor of a single-phase pump. During startup, it keeps the start winding energized to generate the torque needed to bring the motor up to speed. Once the motor reaches its operating RPM, the centrifugal mechanism opens the switch and disconnects the start winding, allowing the motor to run efficiently on the main winding alone. If the switch fails to open, the start winding stays energized and overheats; if it fails to close on startup, the motor won't develop enough torque to turn over — both conditions can cause permanent winding damage if left unaddressed.
