The curve 0.6 0.5 allows the calculation of the power losses at load 0.4 currents lower than the 0.3 rated current. The correc0.2 tion factor, Kp, is given as a function of the RMS load current, Ib, in % of the 0.1 rated current. 30 40 Agency Information: CE, Designed and tested to IEC 60269: Part 4, UL Recognized. 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). 1.4 1.2 103 9 8 7 6 Ib 50 60 70 • • • • 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 80 90 100% Dimensions (mm) Type 00B/60, 00BTN/60 1mm = 0.0394” / 1” = 25.4mm M8 Did You Know? 6 The world’s largest hydroelectric station at Itaipu on the borderline between Brazil & Paraguay is protected by Cooper Bussmann high speed fuses, 3000V, 400A. 64 30 54 Max 48 62 Indicator For product data sheets, visit www.cooperbussmann.com/products/datasheet.asp 147 High Speed Fuses Square body flush end contact — 690V (IEC): 25-400A Size 00 — 25-400A: 690V Catalog Numbers Electrical Characteristics Time-Current Curve Watts Loss 6 7 9 10 12 15 20 25 30 35 45 55 60 70 • Watts loss provided at rated current. • Microswitch indicator ordered separately.
