For other voltages, the clearing I2t is found by multiplying by correction factor, K, given as a function of applied working voltage, Eg, (RMS). This curve gives the peak arc voltage, UL, which may appear across the fuse during its operation as a function of the applied working voltage Eg, (RMS) at a power factor of 15%. Watts loss at rated current is given in the electrical characteristics. The curve allows the calculation of the power losses at load currents lower than the rated current. The correction factor, Kp, is given as a function of the RMS load current, Ib, in % of the rated current. *Rated voltage 900V 1,5 3 UL 2,5 2 1,8 1,6 1,4 1,2 103 K * 1,0 0,5 0,3 0,4 0,3 0,2 0,15 4 0,2 Eg 600 700 800 900 Eg 3 1000 Kp 0,8 0,7 0,6 0,5 8 7 6 5 0,4 500 1,0 500 600 700 800 900 0,1 30 1000 Ib 40 50 60 70 80 90 100% Dimensions Flush End Contact Type –BKN/- and –GKN/Size 1*BKN/75+GKN/75 1BKN/75+GKN/75 2BKN/75+GKN/75 3BKN/75+GKN/75 B 74 74 74.4 75.4 Max D 61 69 77 92 E 43 52 59 74 F M8 M8 M10 M12 F§ 5/16” – 18 UNC-2B 5/16” – 18 UNC-2B 3/8” – 16 UNC-2B 1/2” – 13 UNC-2B Min G 5 8 10 10 H ø17.5 ø20 ø24 ø30 Size A B 3BKN/90+GKN/90 80.3 91.4 § Valid for fuses type –GKN/Dimensions in mm 1 mm = 0.0394” 1” = 25.4 mm Max D 92 E 74 F M12 F§ 1/2” – 13 UNC-2B Min G 10 H ø30 2-25-02 SB01407 A 72.5 73.2 73.2 73.3 Form No.170M Page 2 of 4 BIF Doc #720080 BIF Document 720080 3 Size The partial dotted curves are for fuses designed to give part range protection (aR protection).
