IH=Hold current-maximum current at which the device will not trip at 23℃ still air. IT=Trip current-minimum current at which the device will always trip at 23℃ 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 (Vmax). Pd=Typical power dissipated from device when in the tripped state in 23℃ still air environment. RMIN=Minimum device resistance at 23℃.

R1MAX=Maximum device resistance at 23℃, 1 hour after tripping . Physical specifications:
