1 / 2 page  For product data sheets, visit www.cooperbussmann.com/datasheets/ulcsa High Speed Fuses 148 Arc Voltage 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%. Power Losses 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. Features and Benefits • Excellent DC performance • Low arc voltage and low energy let-through (I2t) • Low watts loss • Superior cycling capability Typical Applications • DC common bus • DC drives • Power converters/rectifiers • Reduced voltage starters Square Body Flush End Contact — 1000V (IEC): 50–1400A 1000V (IEC) 50–1400A Specifications D De es sc crriip pttiio on n:: Square body flush end contact high speed fuses. D Diim me en ns siio on ns s:: See dimensions illustration. R Ra attiin ng gs s:: Volts: — 1000Vac. Amps: — 50-1400A IR: — 150kA (Est. 300kA) RMS Sym.

Electrical Characteristics Total clearing I2t The total clearing I2t at rated voltage and at power factor of 15% are given in the electrical characteristics. For other voltages, the clearing I2t is found by multiplying by correction factor, K, given as a function of applied working voltage, Eg, (rms). 1,5 1,0 0,5 0,4 0,3 0,2 K Eg 500 600 700 800 900 1000 *Rated voltage 900V * 3 2,5 2 1,8 1,6 1,4 1,2 10 3 8 7 6 5 4 3 UL Eg 500 600 700 800 900 1000 Dimensions (mm) Type –BKN/- and –GKN/- S Siiz ze e A A B B M Ma ax x D D E E F F F F** ((iin n)) M Miin n G G H H 1*BKN/75+GKN/75 72.5 74 61 43 M8 5 ⁄16” – 18 UNC-2B 5 ø17.5 1BKN/75+GKN/75 73.2 74 69 52 M8 5 ⁄16” – 18 UNC-2B 8 ø20 2BKN/75+GKN/75 73.2 74.4 77 59 M10 3 ⁄8” – 16 UNC-2B 10 ø24 3BKN/75+GKN/75 73.3 75.4 92 74 M12 1 ⁄2” – 13 UNC-2B 10 ø30 3BKN/90+GKN/90 80.3 91.4 92 74 M12 1 ⁄2” – 13 UNC-2B 10 ø30 * Valid for fuses type –GKN/-. 1mm = 0.0394” / 1” = 25.4mm 1,0 0,8 0,7 0,6 0,5 0,4 0,3 0,2 0,15 0,1 K p Ib 30 40 50 60 70 80 90 100% For Other Voltage Ratings in This Body Style • See pages 124 (690V/700V) and 162 (1250V/1300V) |
