I_H=Hold current-maximum current at which the device will not trip at 23℃ still air.

I_T=Trip current-minimum current at which the device will always trip at 23℃ still air.

T _trip=Maximum time to trip(s) at assigned current.

I_MAX= Maximum fault current device can withstand without damage at rated voltage (V_MAX).

V_MAX=Maximum voltage device can withstand without damage at its rated current.

P_{D Typ}=Typical power dissipated from device when in tripped state in 23℃ still air environment.

R_MIN=Minimum device resistance at 23℃.

R1_MAX=Maximum device resistance at 23℃, 1 hour after tripping
