Ih=Hold current-maximum current at which the device will not trip at 23°C still air. It=Trip current-minimum current at which the device will always trip at 23°C still air. 

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

I Max.= Maximum fault current device can withstand without damage at rated voltage (V Max). Pd=Typical power dissipated from device when in tripped state in 23°C still air environment. 

RMin.=Minimum device resistance at 23°C. 

R1Max.=Maximum device resistance at 23°C, 1 hour after tripping. Physical specifications:
