  Note :
V max : Maximum voltage device can withstand without damage at rated current.
I max : Maximum fault current device can withstand without damage at rated voltage.
I hold : Hold current; maximum current device will sustain for 30 mins without tripping in 25ºC still air.
I trip : Trip current; minimum current at which the device will trip in 25ºC still air.
R min : Minimum resistance of device in initial (un-soldered) state.
R max : Maximum resistance of device in initial (un-soldered) state.
P(d) : Power dissipated from device when in the tripped state at 25ºC still air.
 
Caution :
  Operation beyond the specified rating may result in damage and possible arcing and flame.
