High Speed Fuses Square Body DIN 43 620 — 690V/700V (IEC/UL): 40-1000A 690V/700V (IEC/UL) 40-1000A 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%. Specifications Description: Square body DIN 43 620 blade style high speed fuses. Dimensions: See dimensions illustration. Ratings: Volts: — 690Vac (IEC) — 700Vac (UL) Amps: — 40-1000A IR: — 200kA RMS Sym. Ag ency Information: CE, Designed and tested to IEC 60269: Part 4, UL Recognized. 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. 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). • • • • 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 For Full Range Fuses in This Body Style • See page 140 Dimensions (mm) Type DIN 1*, DIN 2, DIN 3 Size 1* 2 3 A 69 69 68 B 135 150 150 D 58 71 88 A E 45 55 76 F 40 48 60 H 20 26 33 Indicator H 1mm = 0.0394” / 1” = 25.4mm D F B E 132 For product data sheets, visit www.cooperbussmann.com/datasheets/ulcsa 6 High Speed Fuses Square Body DIN 43 620 — 690V/700V (IEC/UL): 40-600A Size 1* — 40-630A: 690V Catalog Numbers Siz e 1* 2 3 Electrical Characteristics Rated I2t (A2Sec) Current Clearing RMS-Amps Pre-arc at 660V 40 40 285 50 78 550 63 120 850 80 185 1350 100 360 2600 125 550 3900 160 1150 8250 200 2300 16500 250 4350 31000 315 7300 52000 350 10000 73000 400 16000 115000 450 21500 155000 500 27000 190000 550 33500 240000 630 48500 345000 700 69500 495000 400 11000 79000 450 16000 115000 500 21500 155000 550 29000 215000 630 41000 295000 700 60500 430000 800 86000 610000 900 125000 895000 1000 180000 1300000 1100 245000 1750000 500 14000 99500 550 19500 140000 630 31000 220000 700 45000 320000 800 69500 490000 900 100000 720000 1000 140000 985000 1100 190000 1400000 1250 300000 2150000 1400 380000 2700000 1500 470000 3350000 1600 585000 4150000 Time-Current Curve Watts Loss 4 4.5 6.5 8.5 10 11 12 12.5 16 20 21.5 60 26.3 28.5 33 37.5 39 29 32 34 36 42 43 48 52 53 56 43 44 45 46 48 50 56 57 61 70 72 74 • Watts loss provided at rated current. • Microswitch indicator ordered separately.
