I hold = Hold current: maximum current device will pass without tripping in 25℃ still air.

I trip = Trip current: minimum current at which the device will trip in 25℃ 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 (V max).

P d typ. = Typical power dissipated from device when in the tripped state at 25℃ still air.

T trip = Maximum time to trip(s) at assigned current reflow soldering of 260℃ for 20 sec.

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

R 1max = Maximum resistance of device at 25℃ measured one hour after tripping or reflow soldering of 260℃ for 20 sec.

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