Hold Current: maximum current device will sustain for 4 hours without tripping in 20C still air. Trip Current: minimum current at which the device will trip in 20C still air. Maximum voltage device can withstand without damage at rated current (Imax) Maximum fault current device can withstand without damage at rated voltage (Vmax) Power dissipated from device when in the tripped state at 20C still air. Minimum resistance of device in initial (un-soldered) state. Maximum measured resistance in the non-tripped state 1 hour after reflow with reflow conditions of 245C for 20 sec.
CAUTION: Operation beyond the specified ratings may result in damage and possible arcing and flame.
