Notes
1. The maximum current at which the device will not trip at 25°C in still air.
2. The minimum current at which the device will always trip at 25°C in still air.
3. The maximum interrupt voltage the device can withstand without damage at the rated current.
4. The maximum fault current the device can withstand without damage at the rated voltage.
5. The maximum time to trip at the assigned current.
6. The typical amount of power dissipated by the device when in state air environment.
7. The minimum device resistance at 25°C prior to tripping.
8. The maximum device resistance at 25°C measured one hour post reflow.
