Rockwell Automation: Short-Circuit Current Ratings

What is short-circuit current rating (SCCR)? The maximum available short-circuit current an electrical component can sustain without the occurrence of excessive damage when protected with an overcurrent protective device. Determining the SCCR of a complete industrial control panel or control switchgear can be challenging, especially if proper considerations are not made during the initial stages of the component selection process.
