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 rated current.
IMAX= Maximum fault current device can withstand without damage at rated voltage (V max).
Pd=Typical power dissipated from device when in the tripped state in 23c.gif (75 ????) still air environment.
RMIN=Minimum device resistance at 23.
R1MAX=Maximum device resistance at 23 1 hour after tripping.
