The Wacker Neuson Fuse is a genuine OEM fuse designed for the HI750 and HI900 series indirect-fired air heaters. This is a direct OEM replacement sourced from Wacker Neuson, covering diesel, natural gas, LP, and DGM configurations across both the HI750 and HI900 product families — including skid-mounted and surge brake variants. Correct fuse rating and fitment are confirmed for all listed models, so you can install with confidence. If your indirect air heater is exhibiting electrical protection issues or the existing fuse has blown, part number is the verified replacement to restore proper operation.
Key Features
- Correct Amperage Rating for the Circuit — Genuine OEM spec ensures the fuse opens at the precise current threshold engineered for the HI750 and HI900 electrical systems, protecting downstream components.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson; identical to the component installed at the factory across all covered heater configurations.
- Broad HI-Series Coverage — Fits a wide range of HI750 and HI900 models including diesel, natural gas, LP, DGM, skid-mounted, and surge brake variants.
- Drop-In Electrical Replacement — Matches the original fuse holder size and terminal type, allowing straightforward installation without modification to the fuse block or wiring harness.
- Electrical Circuit Protection — A correctly rated fuse prevents overcurrent damage to the heater's control board and ignition circuitry; an improperly rated substitute risks component failure or fire hazard in fuel-burning equipment.
A fuse is the first line of defense in any electrical circuit, designed to interrupt current flow when amperage exceeds a safe level. In an indirect-fired air heater like the HI750 and HI900 series, the fuse protects the control circuitry — including the ignition system, fuel control solenoids, and safety lockout components — from damage caused by short circuits or electrical overloads. When a fuse blows, the heater will lose power to one or more of these systems and may fail to start or shut down unexpectedly; replacing it with the correct OEM-rated fuse restores normal protection and operation.
