I hold = Hold current: maximum current device will pass without tripping in 20°C still air.
trip =Trip current: minimum current at which the device will trip in 20°C still air.
max = Maximum voltage device can withstand without damage at rated current (I max)
max = Maximum fault current device can withstand without damage at rated voltage (Vmax
d = Power dissipated from device when in the tripped state at 20°C still air.
Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.
R min = Minimum resistance of device in initial (un-soldered) state.
