Typical Application Scenarios

  • 100‑125V DC new‑energy vehicle main‑battery short‑circuit protection
  • RV, yacht and marine vessel 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

Match 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 Notes

  • This is short‑circuit‑only protector and cannot provide overload‑protection function.
  • Disconnect main power before installation or replacement to avoid accidental short‑circuit risk.
  • Follow mounting torque 12.0 Nm ±1 Nm; loose contact will result in abnormal over‑heating under heavy‑current load.
  • Temperature derating assessment is required for enclosed high‑temperature installation compartments.
  • Only replace with same‑specification protector to maintain original circuit‑protection performance.
