I hold = Hold current: maximum current device will pass without tripping in 23C still air. I trip = Trip current: minimum current at which the device will trip in 23C still air. V max = Maximum voltage device can withstand without damage at rated current (Imax) I max = Maximum fault current device can withstand without damage at rated voltage (Vmax) Pd = Power dissipated from device when in the tripped state at 23C still air.
R min = Minimum resistance of device in initial (un-soldered) state. R 1max = Maximum resistance of device at 23C measured one hour after tripping. Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.
