V _max = Maximum voltage device can withstand without damage at rated current (I max)
I _max = Maximum fault current device can withstand without damage at rated voltage (V_max)
P _d = Power dissipated from device when in the tripped state at 20°C still air.
R _min = Minimum resistance of device in initial (un-soldered) state.
R = Typical resistance of device in initial (un-soldered) state.
