Typical Applications
- 70V DC new‑energy vehicle main‑battery short‑circuit protection
- RV, yacht and marine high‑capacity battery‑bank DC‑system protection
- Heavy‑duty special‑vehicle and mobile‑equipment power‑distribution circuits
- Off‑grid & on‑grid energy‑storage DC main‑circuit short‑circuit protection
Pair this ceramic car fuse anl mega bolt down fuses for automotive circuits with our bolt‑down fuse holders for complete power‑distribution assembly.
Installation & Safety Remarks
- This unit is short‑circuit protector only, cannot provide overload‑protection function.
- Disconnect main power supply before installation or replacement to avoid accidental short‑circuit risk.
- Observe mounting torque 12.0 Nm ±1 Nm; loose contact will cause over‑heating under heavy‑current load.
- Temperature derating assessment shall be performed for enclosed high‑temperature installation compartments.
- Replace only with identical‑specification protector to keep original circuit‑protection performance.
