The Wacker Neuson Thermal Switch is a genuine OEM component designed for the PS2-1503, PS3-1503, PS2-2203, and PS3-2203 series submersible pumps. As a direct factory replacement, this switch carries the same specifications as the original part, ensuring proper thermal response within the pump's motor protection circuit. Wacker Neuson OEM parts are manufactured to meet the exact design requirements of each machine in the PS series lineup, making the the correct choice when restoring pump protection to its original operating standard. This Thermal Switch is confirmed to fit a wide range of PS series submersible pump configurations spanning 50mm/2in and 75mm/3in discharge sizes across multiple voltage ratings.
Key Features
- Genuine OEM Thermal Trip Accuracy — Calibrated to the same activation temperature as the original switch, ensuring the motor cuts out at the correct threshold — not too early, not too late.
- Drop-In Motor Protection Replacement — Connects directly into the existing motor wiring harness on PS series submersible pumps with no splicing or adapter required.
- Broad PS Series Compatibility — Fits PS2-1503, PS3-1503, PS2-2203, and PS3-2203 models across 400V/50Hz, 440V/60Hz, and other voltage configurations.
- Protects Against Overheating Damage — A correctly functioning thermal switch interrupts power before motor windings reach a damaging temperature, preventing costly burnout and pump failure.
- Critical Electrical Safety Component — Thermal protection switches are a safety-rated element of submersible pump motor circuits; using a correctly rated OEM replacement maintains the intended protection level of the pump's electrical system.
A thermal switch is a temperature-activated safety device built into the motor of a submersible pump. When the motor reaches an unsafe operating temperature — caused by running dry, restricted flow, or excessive load — the switch interrupts the electrical circuit, cutting power before heat can damage the motor windings. Once the motor cools to a safe temperature, the switch resets and allows normal operation to resume. A failed or incorrectly rated thermal switch can either allow the motor to overheat and burn out, or trip prematurely and cause unexplained shutdowns — both outcomes lead to costly downtime and potential pump replacement.
