The Wacker Neuson Fuse is a genuine OEM component designed for the HI 770 XHD series indirect air heaters, including Arctic Bear XHD and HI770XHD models. As a direct OEM replacement, this fuse is sourced from Wacker Neuson and matches the original specification installed at the factory — ensuring the correct current rating and form factor for your machine. Compatible across multiple HI 770 XHD configurations, including 2x12, 1x16, and 1x20 duct arrangements as well as Extra Heavy Duty Air Heater variants. If your heater is blowing fuses or failing to power on, part number is the correct replacement to restore proper electrical protection.
Key Features
- Correct Current Rating for HI Series Heaters — Matched to the original electrical specification of the HI 770 XHD, protecting the heater's control circuit from overcurrent damage.
- Genuine OEM Quality — Sourced directly from Wacker Neuson, this fuse meets the exact interrupt capacity and form factor required for safe, proper operation in these diesel indirect air heaters.
- Drop-In Replacement — Fits the original fuse holder without adaptation, making field replacement fast and straightforward.
- Broad HI 770 XHD Coverage — Compatible with Arctic Bear XHD, Arctic Bear XHD NS, and multiple HI770XHD machine configurations across 2x12, 1x16, and 1x20 duct layouts.
- Electrical Safety Protection — A correctly rated fuse is the primary safeguard against wiring damage and control board failure; an incorrect or bypassed fuse puts the entire heater electrical system at risk.
A fuse protects the electrical circuits in your indirect air heater by interrupting current flow if a fault or overload occurs. In a diesel indirect heater like the HI 770 XHD, the fuse safeguards the control electronics and ignition circuitry that manage burner operation and airflow. If the fuse fails or is replaced with an incorrect rating, the heater may fail to start, shut down unexpectedly, or — in the case of an undersized replacement — leave critical components exposed to damaging current surges.
