             Exceptionally low I T, Watt losses.
             Non-magnetic construction,
             Highly reliable low voltage
             Trip-indicator system, conformity to UL,
             IEC, DIN and VDE standards.
             Increased technical performance
                   • Highter ratings
                   • Reduction in volume and weight







             This fuse preselection table indicates, for each size:

             - rated current (or rating) In
                           2
             - pre-arcing I t (I tp) at 1 ms
                        2
                                2
             - total operating I t (I tt) at 660 V, f=50Hz cos ϕ=0.15, and for a total operating time from 8 to 10 ms
                             2
             - dissipated power Pn at the rated current In, and at 0.8 In, in steady state
             - breaking capacity at various voltages, checked by tests
              made in accordance with IEC and American standards.
