Have you looked at the various flameproof resistor offerings? Flameproof types are frequently used as a fusible element - it's by virtue of the fact that they abruptly go open-circuit under overload, that they fail to reach smoke / ignition temperature.
Check some datsheets and see what kind of specs they publish for that service.. might be an ideal way to go.
