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.

VMAX=Maximum voltage device can withstand without damage at it rated current (IMAX).

IMAX= Maximum fault current device can withstand without damage at rated voltage (VMAX).

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 after tripping or reflow soldering of 260℃ for 20 seconds.
