The Wacker Neuson High Limit 2 Cable is a genuine OEM component designed for the HI750 and HI900 series mobile indirect fired air heaters. As a factory-sourced part, it delivers the exact electrical specifications and connector configuration required by these heaters, ensuring proper integration with the high-limit safety circuit. This cable is confirmed to fit a wide range of HI750 and HI900 configurations including diesel, natural gas, LP, skid-mounted, and surge brake variants.
Key Features
- Correct Electrical Specification: — Manufactured to OEM-specified conductor gauge, insulation rating, and terminal geometry to maintain accurate high-limit circuit continuity in demanding heat environments.
- Direct Plug-In Replacement: — Connectors and cable routing match the original assembly, allowing straightforward installation without splicing or modification to the heater wiring harness.
- Broad HI750 and HI900 Series Coverage: — Fits diesel, natural gas, LP, skid-mounted, surge brake, and heavy-duty variants across both the HI750 and HI900 model families.
- Protects High-Limit Sensor Function: — A failed or degraded cable can interrupt the high-limit signal, causing nuisance shutdowns or — more critically — preventing the heater from shutting down when overtemperature conditions occur.
- Safety-Critical Electrical Compliance: — The high-limit circuit is a core safety system on indirect fired heaters; using a genuine OEM cable ensures the circuit responds correctly to overtemperature events as designed.
- Genuine Wacker Neuson OEM Part: — Sourced directly from Wacker Neuson, part number 5000183283 is the same component installed at the factory — no substitutions or approximations.
The high limit cable connects the high-limit temperature sensor to the heater's control board, carrying the signal that tells the unit to shut down if internal temperatures exceed a safe threshold. On indirect fired air heaters like the HI750 and HI900 series, this circuit is essential for both safe operation and reliable heat output — if the cable develops a fault, a break in continuity, or a poor connection, the heater may fail to start, shut down unexpectedly, or lose the ability to respond to an overtemperature condition. Replacing a worn or damaged cable with the correct OEM part restores the integrity of this safety-critical circuit and keeps the heater operating as designed.
