Hi Kimura,
I’m not sure what you mean by your question. An ideal fuse would have infinite breaking capacity, but that’s not possible. All fuses have a breaking capacity (also known as the interrupting rating), as it is a matter of the physics of the device. That spec refers to the maximum current a fuse can safely interrupt. Anything above this can have unpredictable results, including uninterrupted arcing and/or physical destruction of the fuse body, possibly including explosion.
The breaking capacity for the 3 Amp 3AB fuse is 100A at 250V or 10,000A at 125V, as rated by UL and CSA. This comes from the Safety Agency Approvals table on the first page of the datasheet.
