That last number is the whole point. A LiFePO4 bank at 48V can deliver several thousand amps into a dead short, and in direct current the arc does not extinguish on its own at every zero crossing the way it does in AC. A fuse has to pull it apart by itself. This is why Class T is the standard choice on battery banks in marine work and in professional off-grid, and why a fuse rated only for automotive DC voltages is the wrong tool here.\u003c\/p\u003e\n\n\u003cdiv class=\"cft-box2\"\u003e\n\u003cp style=\"margin:0;font-size:16px;\"\u003e\u003cstrong\u003eTwo mechanical formats, not interchangeable.\u003c\/strong\u003e The 110-200A sizes have an 8mm hole with 42.86mm centres; the 225-400A sizes have a 10mm hole with 46.7mm centres.
