Match this gfevg dual‑circuit battery fuse holder with our high‑current bolt‑on battery fuses to build complete dual‑loop heavy‑current battery‑protection assembly.
Installation & Safety Instructions
- Disconnect battery / DC main‑power before fuse installation or replacement to prevent short‑circuit hazard.
- Apply correct tightening torque for M8 fasteners; insufficient torque will produce over‑heating under heavy‑current load.
- Each single circuit must not exceed 400A rated current; total dual‑circuit combined load shall not exceed 800A.
- Select matched battery‑protection fuse according to actual continuous working‑current for each independent circuit.
- Carry‑out temperature derating assessment for sealed high‑temperature installation compartments.
- Regularly inspect fastener tightness for vehicle / marine vibration‑prone operating environments.
