Fuse interruption rating
WebOct 2, 2024 · The short-circuit current rating is the maximum amount of RMS (Root-Mean-Squared) current an electrical component can handle when using an overcurrent … WebJan 3, 2013 · So fuses have to be rated for the type of current they interrupt. Many fuses have both AC and DC ratings; the DC rating is always less. Put a 100-a AC fuse on a DC circuit, and there's a real good chance the fuse will not be able to interrupt a 100-a DC fault. The fuse will blow, but the current will continue to flow. T.
