Short-Circuit Current Rating (SCCR) is a crucial safety value indicating the maximum short-circuit current an electrical component, device, or assembly can safely endure without posing a shock or fire hazard.

Essentially, SCCR reveals how much electrical force equipment can withstand during a fault, such as a direct short circuit, before a hazardous failure occurs. This rating is mandatory for industrial control panels and various electrical equipment, ensuring that the equipment can handle the maximum available fault current at its installation site, thereby preventing dangerous breakdowns.
