Application Scenarios
- New‑energy vehicle high‑voltage DC main‑circuit short‑circuit protection
- Energy‑storage battery‑bank short‑circuit protection for 12‑150V DC systems
- Heavy‑duty special‑purpose vehicle & mobile‑equipment DC power‑distribution
- Large‑size marine high‑power DC short‑circuit protective application
Pair this ceramic high‑temp heavy‑duty fork bolt‑down automotive fuse with our bolt‑down fuse holders for complete power‑distribution assembly.
Installation & Important Remarks
- This unit functions as short‑circuit protector only, cannot provide overload‑protection.
- Cut off main power supply before installation; tighten bolts to 10 Nm ±1 Nm to avoid over‑heating caused by loose‑connection.
- Working ambient range:‑40℃ ~ +125℃; temperature derating assessment required for enclosed high‑temperature compartments.
- Critical warning: Product remains in development phase. Do NOT deploy in mass‑production projects without formal sample‑validation and release documentation.
