I _hold = Hold current: maximum current device will pass without tripping in 20°C still air.
I _trip = Trip current: minimum current at which the device will trip in 20°C still air.
V = Maximum voltage device can withstand without damage at rated current (I max)
max
I = Maximum fault current device can withstand without damage at rated voltage (V )
