1A fuse blows instantly when 10A goes through it?

[treez]

Schurter 3403.0166 (1A) fuse gives no data for “time to break” for currents above 10A.
Is this because it breaks instantly foR currents above 10A?

Please notice that the data sheet gives only pre-arcing time. Total time to break is longer.

Thanks, the i^2.t for the fuse is 2.8, so that means 740A could flow through it for 5us and it wouldnt blow. Seems too much?

Two points to consider
- fuse might not interrupt the current if breaking capacity is exceeded
- after the fuse element has melted, an arc of at least several ms can occur, depending on the circuit I/V characteristic

What did Schurter say when y0u asked them this? :thumbsup:
