The Wacker Neuson Thermal Switch is a genuine OEM component designed for the PS23703, PS33703, and PS43703 series submersible pumps. Sourced directly from Wacker Neuson, this thermal switch meets the exact electrical specifications required for 575V/60Hz pump operation across the 50mm, 75mm, and 100mm submersible pump models. As a genuine OEM part, it is built to the same standards as the original component installed at the factory, ensuring correct trip thresholds and circuit protection behavior. Verify your pump model and serial number against the fitment list before ordering to confirm compatibility.
Key Features
- Correct Trip Threshold: — Calibrated to the precise over-temperature activation point required for 575V submersible pump motor protection — not a generic thermal cutout.
- Genuine OEM Part: — Manufactured by Wacker Neuson; part number 5000150574 matches the original component specification for direct installation without guesswork.
- Broad Submersible Pump Compatibility: — Fits the PS23703 (50mm/2 in), PS33703 (75mm/3 in), and PS43703 (100mm/4 in) 575V/60Hz submersible pump models.
- Motor Protection You Can Count On: — A functioning thermal switch interrupts power when the motor exceeds safe operating temperature; a failed switch leaves the motor exposed to heat-related burnout and costly replacement.
- Electrical Safety Critical Component: — Thermal protection switches are a primary safeguard in submersible motor circuits; using an OEM-spec replacement maintains the intended protection rating of the pump assembly.
The thermal switch is a temperature-sensitive safety device wired into the motor circuit of a submersible pump. When the motor reaches an unsafe operating temperature — caused by dry running, overload, or restricted flow — the switch opens the circuit and cuts power before heat damage can occur. Once the motor cools to a safe level, the switch resets and allows the pump to resume operation. A faulty or missing thermal switch removes this automatic protection, leaving the motor vulnerable to irreversible winding damage and pump failure.
