The Wacker Neuson Fuse is a genuine OEM fuse designed for the HI 90, HI 90HD, and HI 120 indirect-fired air heaters. Sourced directly from Wacker Neuson, this is the exact fuse specified for these heater models, ensuring a correct, drop-in fit with no guesswork on rating or form factor. It protects the heater's electrical circuit from overcurrent events, keeping the control system and ignition components safe during demanding jobsite heating operations. Keep a spare on hand — fuse replacement is one of the quickest fixes in the field, and having the right part ready means your heater is back up fast when it matters most.
Key Features
- Correct Overcurrent Rating: — Matched to the exact amperage specification required by the HI-series heater electrical system, so circuit protection performs as engineered.
- Genuine OEM Part: — Supplied by Wacker Neuson as part number 5200024750, identical to the fuse installed at the factory — same rating, same form factor, same terminal fit.
- Fits HI 90, HI 90HD, and HI 120: — Verified fitment across the HI 90, HI 90HD, and HI 120 indirect-fired air heater models, covering the most common units in this heater family.
- Electrical System Protection: — A properly rated fuse prevents overcurrent damage to control boards, ignition components, and wiring harnesses — a failed or incorrect fuse can leave the entire heater inoperable or cause downstream electrical damage.
- Critical Safety Component: — Fuses are a primary line of defense against electrical faults in fuel-burning equipment; using the correct OEM-specified fuse maintains the integrity of the heater's safety circuit design.
A fuse is the electrical system's first line of defense, interrupting the circuit instantly when current exceeds a safe level. In an indirect-fired air heater like the HI 90 or HI 120, the fuse protects sensitive control electronics and ignition components from damage caused by surges or shorts. When a fuse blows, the heater will typically fail to start or shut down completely — replacing it with the correct OEM-rated fuse restores normal operation and ensures the protection circuit continues to function as intended.
