IH=Hold current: maximum current at which the device will not trip at 25℃ still air.
IT=Trip current: minimum current at which the device will always trip at 25℃ still air.
Vmax=Maximum voltage device can withstand without damage at rated current.
Imax=Maximum fault current device can withstand without damage at rated voltage.
Ttrip=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℃ prior to tripping.
Rmax=Maximum device resistance at 25℃ prior to tripping.
