IH = Hold current: maximum current at which the device will not trip at 25°C still air.
IT = Trip current: minimum current at which the device will always trip at 25°C still air.
Vmax = Maximum interrupt voltage device can withstand without damage at rated current.
Imax = Maximum fault current device can withstand without damage at rated voltage.
Max. Time-to-trip = Maximum time to trip(s) at assigned current.
Pdtyp = Typical power dissipation: typical amount of power dissipated by the device when in state air environment.
Rmin = Minimum device resistance at 25°C prior to tripping.
Rmax = Maximum device resistance at 25°C prior to tripping.
R1max = Maximum device resistance measured one hour post-trip at 25°C
