Trip current: minimum current at which the device will trip in 20 C still air. Maximum voltage device can withstand without damage at rated current (I max) Maximum fault current device can withstand without damage at rated voltage (Vmax) Pd = Power dissipated from device when in the tripped state at 20 C still air. Minimum resistance of device in initial (un-soldered) state. R min= Maximum resistance of device at 20 C measured one hour after tripping for 20 s. R 1max= Caution: Operation beyond the specified rating may result in damage and possible arcing and flame. Specifications are subject to change without notice Order Information Qty.
