The Wacker Neuson Relay is a genuine OEM component designed for the HI260 indirect-fired air heater series. As a factory-sourced part, it meets the exact electrical specifications required by the HI260 heating system, ensuring correct switching behavior and consistent heater operation. This relay fits both the standard HI260 and the HI260 Oil with Tank configurations, making it the right choice for operators running either variant on their jobsite.
Key Features
- Correct Switching Specs: — Genuine OEM construction ensures the relay operates at the precise voltage and current ratings the HI260 control circuit requires — no guesswork on electrical compatibility.
- Direct HI260 Replacement: — Engineered to drop into the same mounting position and wiring harness connection as the original, covering both the standard HI260 and the HI260 Oil with Tank models.
- Heater Control Integrity: — A functioning relay is what allows the HI260's control system to switch burner and fuel circuits on and off cleanly; a failed relay can cause the heater to not ignite, run continuously, or shut down unexpectedly.
- Fuel System Safety Compliance: — In indirect-fired heater applications, the relay governs fuel circuit switching. Using a correctly rated OEM relay maintains the safe, controlled operation the heater was designed around.
- Genuine Wacker Neuson OEM Part: — Sourced directly from Wacker Neuson, part number 5100015847 is the same component installed at the factory — not an approximation.
The relay in an indirect-fired air heater acts as an electrically controlled switch, allowing the heater's control board to open and close high-current circuits — such as the fuel pump or ignition system — without routing that load directly through the control electronics. When a relay fails, the circuit it governs either stays open (causing the heater to not start or lose a key function) or fails closed (causing uncontrolled operation). Replacing a worn or failed relay with the correct OEM part restores proper electrical switching and keeps the HI260 operating as intended throughout demanding heating seasons.
