The Multiquip 020CX400447 is a genuine OEM Centrifugal Switch CX-400 designed for CX400 submersible pumps. Sourced directly from Multiquip, this switch is the exact component specified for your machine — no guesswork on compatibility. It is a direct OEM replacement, engineered to the same tolerances and specifications as the original part installed at the factory. If your CX400 is failing to start, running rough, or cycling incorrectly, this switch is a common service item worth inspecting first.
Key Features
- OEM-Spec Switching Threshold — Calibrated to the exact RPM activation point required by the CX400 motor, ensuring the start winding cuts out at the correct speed every time.
- Drop-In Replacement — Matches the original mounting configuration and electrical connections of the CX400, so installation is straightforward with no reworking of the motor housing.
- CX400 Submersible Pump Fitment — Confirmed for CX400 series submersible pumps; use part number 020CX400447 to verify fitment before ordering.
- Protects Motor Windings — A correctly functioning centrifugal switch disconnects the start capacitor circuit at the right moment, preventing heat buildup and premature winding failure.
- Electrical Safety Assurance — On a submersible pump operating in wet environments, a faulty centrifugal switch can cause motor overload or failure to shut off — using the correct OEM component maintains safe, predictable motor behavior.
A centrifugal switch is an electromechanical component inside single-phase electric motors that disconnects the start winding from the circuit once the motor reaches a set percentage of its operating speed. During startup, the start winding provides extra torque to get the motor spinning; once running speed is achieved, the centrifugal switch opens the circuit to that winding so the motor runs efficiently on the main winding alone. When this switch fails — either staying closed and overheating the start winding, or failing to close and preventing startup altogether — the motor will not run correctly and can sustain permanent damage if left unaddressed.
