IH=Hold current-maximum current at which the device will not trip at 23°C still air.
IT=Trip current-maximum current at which the device will always trip at 23°C still air.
V MAX=Maximum voltage device can withstand without damage at its rated current.
I MAX=Maximum fault current device can withstand without damage at rated voltage (V MAX).
Pd=Typical power dissipated from device when in the tripped state in23°C still air environment.
R MIN=Minimum device resistance at 23°C.
Figure 1
R1MAX=Maximum device resistance at 23°C, 1 hour after tripping.
