The Wacker Neuson 50A/30A Relay is a genuine OEM electrical relay designed for the TH627 indirect-fired air heater. Sourced directly from Wacker Neuson, this part meets the exact specifications required by the TH627 heating system, ensuring the relay switches current at the correct amperage ratings for safe and consistent operation. It is a direct drop-in replacement verified against OEM parts list 418-02 for the TH627.
Key Features
- Correct Amperage Rating: — Rated at 50A/30A to match the precise switching load requirements of the TH627 heater's electrical circuit — no guesswork on current capacity.
- Genuine OEM Component: — Manufactured to Wacker Neuson's exact electrical specifications, ensuring proper contact resistance and switching performance for this heater's control system.
- Direct OEM Fitment: — Verified against Wacker Neuson parts list 418-02 for the TH627, connecting into the existing relay socket with no modifications to wiring or mounting hardware.
- Protects the Heater's Electrical System: — A correctly functioning relay ensures the burner and fan circuits engage and disengage cleanly; a failed relay can cause the heater to not ignite, run continuously, or trip protection systems.
- Electrical Safety Compliance: — Using a correctly rated OEM relay prevents overcurrent conditions in the control circuit, helping maintain safe heater operation on the worksite.
A relay is an electrically operated switch that allows a low-current control signal to open or close a higher-current circuit. In the TH627 indirect-fired air heater, the 50A/30A relay manages the switching of key electrical loads — such as the burner ignition or blower fan motor — within the heater's control system. When the relay fails or its contacts burn out, the heater may fail to start, lose a critical function mid-operation, or remain locked in an unintended state, disrupting heat output on cold-weather jobsites.
