I_H=Hold current:maximumcurrent at which the device will not trip at 25℃ still air.

I_T=Trip current:minimumcurrent at which the device will nalways at 25℃ still air.

V_max=Maximum voltagedevice can withstand without damage at rated current.

I_max=Maximum faultcurrent device can withstand tithout damage at rated voltage.

T_trip=Maximum time totrip(s) at assigned current.

P_d=Typical powerdissipation:typical amount of power dissipated by the decice when in state airenvironment.

R_min=Minimum deviceresistance at 25℃ prior to tripping.

R_max=Maximum deviceresistance at 25℃ prior to tripping.
