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.
