I H = Hold current—maximum current at which the device will not trip at 20°C.
I T = Trip current—minimum current at which the device will always trip at 20°C.
P d = Typical power dissipation—typical amount of power dissipated by the device when in tripped state in 20°C still air.
R min. = Minimum device resistance at 20°C prior to tripping.
R max. = Maximum device resistance at 20°C prior to tripping.
R 1 max. = Maximum device resistance at 20°C measured 1 hour post trip.
* Device tested at 40 A.
