SCCR
Short-circuit current rating: the maximum fault current the assembly can withstand, marked in kA at a stated voltage
Also defined as
- Datacenter: Short-circuit current rating, the available fault current the SPD can be connected to and still fail safely
- Datacenter: Short-circuit current rating, matched to the available fault current at the connection point
