R min= Minimum resistance of device in initial (un-soldered) state. R 1max= Maximum resistance of device at 20 C measured one hour after tripping for 20 s. Caution: Operation beyond the specified rating may result in damage and possible arcing and flame. NOTE: I hold = Hold current: maximum current device will pass without tripping in 20 C still air. I trip = Trip current: minimum current at which the device will trip in 20 C still air. I max = Maximum fault current device can withstand without damage at rated voltage (Vmax) Order Information Qty.
