The Wacker Neuson Ceramic Fuse is a genuine OEM ceramic fuse designed for the HI 200D, HI 200HD D, HI 300D, and HI 300HD D series diesel indirect-fired air heaters. As a direct factory replacement, this fuse installs exactly as the original, maintaining the correct circuit protection spec for your heater's electrical system. Sourced directly from Wacker Neuson, part ensures full compatibility across all listed HI-series heater models without guesswork or modification.
Key Features
- Correct Amperage Rating for HI-Series Heaters — Genuine OEM spec means this ceramic fuse carries the exact interruption rating required to protect the electrical circuits in Wacker Neuson diesel indirect-fired heaters.
- Drop-In Electrical Fit — Matches the original fuse holder footprint and terminal size, so installation is straightforward with no adapter or rewiring needed.
- Broad HI-Series Compatibility — Fits HI 200D, HI 200HD D, HI 300D, and HI 300HD D diesel indirect air heater models, covering a wide range of job-site heating applications.
- Protects Critical Heater Electronics — A correctly rated fuse prevents downstream electrical damage to burner controls and ignition components when a fault occurs, keeping costly repairs to a minimum.
- Electrical Safety Compliance — Using the correct OEM-rated fuse is essential in fuel-burning heater applications; substituting an incorrect rating can compromise over-current protection and create a fire or equipment hazard.
A ceramic fuse acts as the sacrificial overcurrent protection device within the heater's electrical circuit. When current exceeds a safe threshold — due to a short circuit, component failure, or power spike — the fuse element melts and breaks the circuit, preventing damage to the burner control board, ignition system, and wiring harness. Ceramic fuses are used in higher-temperature or higher-current applications because the ceramic body contains the arc more effectively than a glass type. When a fuse blows, it signals an underlying electrical fault; installing a replacement of the correct rating restores protection while you investigate the cause. Using an incorrect fuse rating risks either nuisance tripping or, more seriously, allowing damaging current levels to pass through unprotected components.
