My fuse doesn't blow out

[giancarlo.croari]

Hello People,

Why doesn't my fuse blow out? What am I forgetting? I simply need something that above I_Limit becomes R=+inf ohm and when I<I_Limit R=0.

Thank you in advance.

Regards.

Hello Giancarlo,

I opened and run your short example (thank you for providing that!) and the fuse blows (see attachment).

How long did you simulate? Which MultiSim version are you using?

Best regards

Christoph
