Look at the graph, it won't actually blow at 440mA. It needs over 1.25A to have any chance of blowing at all.

Well, it depends on both current and time. I blew the fuse in a fraction of a second when I inadvertently tried to measure the current through a 60 W incandescent bulb (500 mA). The switch on current was apparently far more than the fuse could sustain.
Thanks everyone and i hope the replacement is no fake. Its from a source i would consider trustworthy as a component reseller (Conrad) here in germany.
