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). 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°C still air environment. R MIN=Minimum device resistance at 23°C prior to tripping. R1MAX=Maximum device resistance at 23°C measured 1 hour post trip.
