With 600V rating, they can be used in 120/208, 120/240and 277/480V circuits. Length variations relative to case size make the rejection type Fuses .
2 In general, SC Fuses are about the size of the 600V NECfuse type. SC Fuses with ampere ratings above 6A have a degree of overload Time-Delay which permits them to passtemporary overloads. At 200% load, they have a minimumopening time of 12 logo denotes compliance with European Union Low Voltage Directive (50-1000 Vac, 75-1500 Vdc).
