IH=Hold current-maximum current at which the device will not trip at 23℃still air.
IT=Trip current-minimum current at which the device will always trip at 23℃ still air.
V MAX=Maximum voltage device can withstand without damage at it rated current.(I MAX)
I MAX= Maximum fault current device can withstand without damage at rated voltage (V MAX).
Pd=Typical power dissipated-type amount of power dissipated by the device when in the tripped state in 23℃ still air environment.
RMIN=Minimum device resistance at 23℃ prior to tripping.
R1MAX=Maximum device resistance at 23℃ measured 1 hour post trip.
