The Wacker Neuson 5200020305 Timer Module is a genuine OEM component designed for the APT4T and APT4S series submersible pumps. This direct OEM replacement covers multiple configurations including the APT4T Pump with Electric Brake, APT4T Pump with Surge Brake, APT4T Cold Weather variants, APT4S Pump with Skid, and the APT4S Cold Weather model. As a genuine Wacker Neuson part, the 5200020305 is built to the same specification as the unit installed at the factory, ensuring correct electrical behavior and compatibility with the pump's control circuit. Confirm your model number before ordering to ensure the right fit for your specific APT4T or APT4S configuration.
Key Features
- Genuine OEM Electrical Specification — Manufactured to the exact timing and switching parameters required by the APT4T and APT4S control systems, ensuring the module operates within the designed electrical envelope.
- Broad APT Series Coverage — Fits APT4T Electric Brake, APT4T Surge Brake, APT4S with Skid, and Cold Weather variants of each, making it the correct replacement across the APT4T and APT4S pump families.
- Drop-In Control Circuit Replacement — Designed to connect directly into the existing pump control wiring without modification, maintaining the integrity of the original circuit layout.
- Protects Pump Operation Cycles — A functioning timer module governs the pump's run and cycle timing; a failed or degraded module can cause erratic operation, failure to start, or uncontrolled continuous running.
- Electrical System Safety — Correct timer function is critical in electric brake and surge brake pump configurations where improper switching can affect brake engagement and safe pump shutdown.
The timer module controls the switching and cycle timing within the APT series pump's electrical control system. It regulates when the pump activates and deactivates, coordinating operation with the brake system on electric and surge brake models. When the timer module fails or degrades, the pump may not start correctly, run beyond its intended cycle, or fail to engage the brake at shutdown — any of which can interrupt pumping operations or cause premature wear on connected components.
