... The internal resistance of this lightweight, compact overcurrent protection element is low, as long as the steady-state current of the element does not exceed the rated current. The ICP-S, however, turns off ICs instantly if the steady-state current reaches or exceeds the breaking current of the ICP-S. ...

... Refer to the next section, calculate the I in the graph. If the value is in the safety area okay to use the selected ICP model. If the value is, however, beyond the safety area, use an ICP model with higher ratings. • Note: The inspection and selection of the ICP according to the Joule integral value is absolutely based on the results of the approximation of the current wave form ...
