Im not sure where to get the exact thing you want but im pretty sure what you want is something to protect you from fire incase of overheating,is this right,if so home depot sells just the thing,i just bought 10 of them but my room's are not in my home & i wont be going there till monday.
Anyhow the device i speak of is a combo surge supressor/voltage supresser,it senses overheated or shorted out lines & breaks contact by frying a transistor board inside the unit,the unit will not work again once this happens.
They are only $15 each & are backed with a $50,000 gaurantee to gaurd against fire due to overheated lines,i just looked on home depots web site & they ae not showing it,on monday night i'll know the name of these units & post it for you.
