Fuse interruption rating

WebFuses with gG characteristics protect associated cables against both overload and short-circuit current, provided that the current rating of the fuse 1N is equal or less than the current carrying capacity of the cable 1z. In motor circuits, the motor starter will provide the overload protection and the fuses will provide the short-circuit ... Webthree-phase available short-circuit current, and Test B is a single-pole interrupt-ing test at a modest single-phase available short-circuit current of 8660A (Table 1). Then, in addition, to be listed and marked with the higher 65,000A interrupt-ing rating, the circuit breaker must pass the criteria for Test C. Test C is a three-

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.
