When using Amp-Trap 2000® fuses, it’s possible to perform the analysis knowing only the bolted-fault current, if that current is above the minimum shown in the incident energy charts. These charts are based on a model that was tested extensively in our lab under conditions believed to yield worst-case results. Be sure to read the criteria carefully to ensure that these charts apply to your applications. To get projected energies, use our online Arc Flash Calculator.
