I hold = Hold current: maximum current device will pass without tripping in 23°C still air.

I trip = Trip current: minimum current at which the device will trip in 23°C 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 23°C still air.

R min = Minimum resistance of device in initial (un-soldered) state.

R 1max = Maximum resistance of device at 23°C measured one hour after tripping.

Caution: Operation beyond the specified rating may result in damage and possible arcing

and flame.
