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. VMAX=Maximum voltage device can withstand without damage at rated current. IMAX= Maximum fault current device can withstand without damage at rated voltage (V max). 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. |
