Understanding Short Circuit Current Rating (SCCR)
ccipower.comremaining devices in the branch circuit have an SCCR not less than the I P (peak let-through current) of the fuse. Referring to the manufacture’s data sheet or UL508A Supplement SB, Table SB 4.2, for the fuse selected, I P = 42 KA. Consider the branch circuit, namely the SCR power controller. If the manufacturer has not
