The Wacker Neuson 5200020304 is a genuine OEM Timer Module designed for the APT4T and APT4S submersible pump series, including Electric Brake, Surge Brake, and Cold Weather variants. As a direct factory replacement, this module restores precise timing control to your pump system, ensuring the unit cycles correctly under operating conditions. It fits across the APT4T and APT4S model families, covering both standard and cold weather configurations.
Key Features
- OEM-Spec Electrical Control: — Engineered to the exact switching timing and output specifications of the original module, ensuring the pump control circuit functions as designed.
- Drop-In Replacement: — Connects directly to the existing wiring harness on APT4T and APT4S pumps with no re-wiring or adapter required.
- Broad APT Series Fitment: — Confirmed for APT4T (Electric Brake and Surge Brake) and APT4S (standard and Cold Weather) model variants.
- Restores Correct Pump Cycling: — A failed timer module can cause erratic pump operation or complete failure to cycle; replacing it returns the unit to reliable, controlled performance.
- Electrical Safety Compliance: — As a genuine OEM electrical control component, this module meets the original safety and circuit protection requirements for the APT pump series.
The timer module controls the on/off cycling of the pump's motor and brake system, regulating when the unit activates and deactivates based on operating demands. It plays a critical role in protecting the motor from overuse and ensuring the brake engages and releases at the correct intervals. When the timer module fails or degrades, the pump may cycle erratically, fail to start, or not shut down properly — all of which can accelerate motor wear or lead to operational failure on site.
