Fault level must be suitable to safely open the resistor. Option FF parts ≥1W are desgned to blow within 20S at 15x rated power, 20x if<1Ω (preferable if fault level is double this level to ensure quick fusing time). 3. Maximum fault must not exceed 200x W rating, or voltage rating, whichever is less (increased levels avail). 4. For customized fusing, complete RCD’s fuse questionnaire, or advise the desired fusing wattage/current, min/max blow times, continuous power, surge reqts, ambient temp, physical constraints, fault voltage, inductance, etc. 5. Fuse types shouldn’t be mounted in contact with other components or PCB. 6. Residual resistance is ≥100x initial value after fusing. 7. Verify selection by evaluating under the full range of fault conditions. Place resistors inside a protective case when testing under overload.
