I hold = the maximum current when the product does not move in the static air environment at 25℃. I trip = the minimum operating current in the static air environment at 25℃.
V max = the maximum voltage that the component can withstand under the rated current. I max = the maximum current that the component can withstand under the rated voltage.
Pd = the power consumption of the product in the action state in the static air environment at 25℃. Rimin/max = the initial resistance at 25℃ (before welding).
R1max = the maximum resistance after welding for one hour at 25℃.
Caution: Operation beyond the specified rating may result in damage and arc and flame.
