The Multiquip 0201503A4471 is a genuine OEM Centrifugal Switch 1 designed for the ST-2005 submersible trash pump. Sourced directly from Multiquip, this switch matches the exact electrical specifications of the original component, ensuring correct motor starting and protection behavior on your pump. If you're servicing an ST-2005 and need a verified, direct-source replacement, this is the correct part.
Key Features
- Genuine OEM Electrical Specification — Manufactured to the exact switching threshold and contact rating required by the ST-2005 motor, not a generic approximation.
- Direct-Source Multiquip Component — Supplied by Multiquip, this switch installs as a drop-in replacement with no improvised adaptation to the motor wiring or mounting points.
- Confirmed Fitment for ST-2005 — Validated for the Multiquip ST-2005 submersible trash pump; always cross-reference your model and serial tag before ordering.
- Protects Motor Windings from Overload — A correctly functioning centrifugal switch disengages the start winding at the right RPM threshold, preventing heat buildup and winding damage during operation.
- Electrical Safety Compliance — Using the correct OEM switch maintains proper motor protection behavior, which is critical in wet submersible environments where an incorrect component can create an electrical hazard.
A centrifugal switch is a speed-sensitive electrical component mounted on the motor shaft inside a single-phase induction motor. At startup, it keeps the start winding energized to generate the torque needed to bring the motor up to speed. Once the rotor reaches approximately 75–80% of its rated speed, centrifugal force causes the switch to open and disconnect the start winding, allowing the motor to run efficiently on the main winding alone. If the switch fails to open, the start winding remains energized and overheats; if it fails to close, the motor will not start at all. In a submersible trash pump like the ST-2005, reliable switch operation is essential to consistent pump startup and long motor service life.
