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 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 (Vmax  
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 typ = Typical resistance of device in initial (un-soldered) state.  
R 1max = Maximum resistance of device at 20°C measured one hour after tripping or reflow  
soldering of 260°C for 20 sec.  
Caution: Operation beyond the specified rating may result in damage and possible arcing  
and flame.
