I hold = Hold current: maximum current device will pass without tripping in 23°C still air.
R min = Minimum resistance of device in initial (un-soldered) state.
I trip = Trip current: minimum current at which the device will trip in 23°C still air.
R max = Maximum resistance of device in initial (un-soldered) state.
Vint = Maximum voltage the device can withstand without damage at rated current (I max)
R 1max = Maximum resistance of device at 20°C measured one hour after tripping.
Vop= The device regular operation voltage
Caution: Operation beyond the specified rating may result in damage and possible arcing
and flame.
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 23°C still air.
