SCCRs on components and equipment represent the maximum level of short-circuit current that the component or equipment can withstand and is used for determining compliance with …
Determining Short-Circuit Current Rating (SCCR) for Machinery
To help you learn more about how a short-circuit current rating (SCCR) is determined for machinery according to the 2021 edition of the NFPA 79, UL Solutions and Eaton Bussmann …
SCCR: “The maximum short circuit current a component, assembly, or equipment can safely withstand when protected by a specifi c overcurrent protective device, or for a specifi ed time …
Table SB4.1 provides the UL standard default short-circuit current ratings that you can use when your device is not marked or data is not provided by the manufacturer.
As a rule, the smallest short-circuit current is produced by a single-pole short circuit, whereas the largest short-circuit current usually arises through a three-pole short circuit.
