Itrip = Trip Current: minimum current at which the device will trip in 20 °C still air. Vmax = Maximum voltage device can withstand without damage at rated current (Imax) Imax = Maximum fault current device can withstand without damage at rated voltage (Vmax) Pd = Power dissipated from device when in the tripped state at 20 °C still air. RIL = Minimum resistance of device in initial (un-soldered) state. RAT = Maximum measured resistance in the non-tripped state 1 hour after reflow with reflow conditions of 245 °C for 20 sec. CAUTION: Operation beyond the specified ratings may result in damage and possible arcing and flame.
