Maximum current device will not trip in 25°C still air. I trip = Trip Current. Minimum current at which the device will always trip in 25°C still air. V max = Maximum operating voltage device can withstand without damage at rated current (Imax). I max = Maximum fault current device can withstand without damage at rated voltage (V max). Pd = Power dissipation when device is in the tripped state in 25°C still air environment at rated voltage. Ri min/max Test= Minimum/Maximum device resistance prior to tripping at 25°C. R1max = Maximum device resistance is measured one hour post reflow. CAUTION : Operation beyond the specified ratings may result in damage and possible arcing and flame.
