Re: Proper Resistance of a Heated Bed

The PDF shows a trip rating of 18.7A beside the 11A holding rating. So the fuse would trip at 18.7A? But I assume it would not trip instantly at this amperage due to it's construction.

Unfortunately, the datasheet doesn't define what it means by the trip current. But my guess is that it is guaranteed to hold at 11A (i.e. remain in a low-resistance state while passing 11A) and to go into thermal runaway eventually (resulting in high resistance) at 18.7A. So it might trip at anything between 11A and 18.7A. It might trip at less than 11A if the temperature around it is higher than 25C.
