Specifications Description: Square body DIN 43 653 stud-mount high speed fuses. Dimensions: See dimensions illustration. Ratings: Volts: -- 1250Vac (IEC) -- 1300Vac (UL) Amps: -- 50-1400A IR: -- 100kA RMS Sym. Ag ency Information: CE, Designed and tested to IEC 60269: Part 4, UL Recognized. Consult Cooper Bussmann for UL Recognition/CSA Component Acceptance status. The total clearing I2t at rated voltage and at power factor of 15% are 0.5 given in the electrical 0.4 characteristics. For other 0.3 2 voltages, the clearing I t is found by multiplying by 0.2 Eg correction factor, K, 400 600 800 1000 1200 1400 given as a function of applied working voltage, Dashed lines (- - - - - -) apply to the following amperages:. Eg, (rms). Size Amps. 1* 1 2 3 400 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. 1.5 K 1.25 1.0 Total Clearing I t UL Eg 3 Power Losses Electrical Characteristics 2 3 2.5 400A 500-630A 630-1000A 800-1400A 600 800 1000 1200 1400 1.0 Kp 0.8 0.6 0.5 0.4 0.3 0.2 Ib 0.1 30 40 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% For Other Voltage Ratings in This Body Style * See pages 122 (690V/700V) and 146 (1000V) Dimensions (mm) Type -KN/110 Dimensions (mm) Siz e 1* 1 2 3 Type -/110, -TN/110 Siz e 1* 1 2 3 A 80 80 80 81 B 138 138 138 139 D** 58 66 75 90 E 45 53 61 76 H 20 25 25 30 108 A A 80 80 80 81 B 138 138 138 139 D 58 66 75 90 E 45 53 61 76 H 20 25 25 30 1mm = 0.0394" / 1" = 25.4mm C **Microswitch. 1mm = 0.0394" / 1" = 25.4mm A H 11 H D E B 11 D 6 B E E 6 E 160 For product data sheets, visit www.cooperbussmann.com/datasheets/ulcsa High Speed Fuses Square Body DIN 43 653 -- 1250V/1300V (IEC/UL): 50-1400A Catalog Numbers -KN/110 Type K Indicator for Micro 170M3238 170M3239 170M3240 170M3241 170M3242 170M3243 170M3244 170M3245 170M3246 170M3247 170M3248 170M4238 170M4239 170M4240 170M4241 170M4242 170M4243 170M4244 170M4245 170M4246 170M4247 170M5238 170M5239 170M5240 170M5241 170M5242 170M5243 170M5244 170M5245 170M5246 170M5247 170M5248 170M5249 170M5250 170M6238 170M6239 170M6240 170M6241 170M6242 170M6243 170M6244 170M6245 170M6246 170M6247 170M6248 170M6249 170M6250 170M6251 Siz e 1* 1 2 3 Rated Current RMS-Amps 50 63 80 100 125 160 200 250 315 350 400 160 200 250 315 350 400 450 500 550 630 250 280 315 350 400 450 500 550 630 700 800 900 1000 315 350 400 450 500 550 630 700 800 900 1000 1100 1250 1400 Electrical Characteristics I2t (A2 Sec) Clearing Clearing Pre-arc at 1000V at 1250V 135 815 1100 215 1300 1750 420 2500 3350 750 4450 5950 1450 9000 11500 2600 16000 21000 5150 31000 41000 9200 54500 73000 18500 115000 150000 27000 165000 220000 53000 265000 335000 1900 11500 15500 3800 22500 30000 7750 46000 61500 15000 90000 120000 20000 125000 165000 29500 175000 235000 42000 250000 335000 69500 340000 435000 95000 465000 590000 130000 660000 6500 38500 51500 9350 55500 74500 13000 77500 105000 16500 97500 135000 23000 140000 180000 34000 205000 270000 48000 285000 380000 62000 370000 495000 115000 575000 730000 160000 795000 1050000 245000 1200000 1550000 360000 1750000 480000 2350000 9500 58000 77500 13500 81500 110000 19500 120000 160000 31000 185000 245000 39000 235000 310000 55000 325000 435000 83500 495000 665000 115000 705000 940000 205000 995000 1300000 305000 1500000 1900000 450000 2150000 2750000 575000 2800000 3600000 810000 3950000 1250000 6000000 Watts Loss 15 20 25 30 35 40 45 55 60 65 70 45 50 60 65 70 75 80 85 95 100 65 70 75 80 85 90 95 100 110 115 120 125 135 85 90 95 100 105 110 115 120 125 130 135 140 145 150 High Speed Fuses Catalog Numbers -TN/110 -/110 Type T Visual Indicator Indicator for Micro 170M3138 170M3188 170M3139 170M3189 170M3140 170M3190 170M3141 170M3191 170M3142 170M3192 170M3143 170M3193 170M3144 170M3194 170M3145 170M3195 170M3146 170M3196 170M3147 170M3197 170M3148 170M3198 170M4138 170M4188 170M4139 170M4189 170M4140 170M4190 170M4141 170M4191 170M4142 170M4192 170M4143 170M4193 170M4144 170M4194 170M4145 170M4195 170M4146 170M4196 170M4147 170M4197 170M5138 170M5188 170M5139 170M5189 170M5140 170M5190 170M5141 170M5191 170M5142 170M5192 170M5143 170M5193 170M5144 170M5194 170M5145 170M5195 170M5146 170M5196 170M5147 170M5197 170M5148 170M5198 170M5149 170M5199 170M5150 170M5200 170M6138 170M6188 170M6139 170M6189 170M6140 170M6190 170M6141 170M6191 170M6142 170M6192 170M6143 170M6193 170M6144 170M6194 170M6145 170M6195 170M6146 170M6196 170M6147 170M6197 170M6148 170M6198 170M6149 170M6199 170M6150 170M6200 170M6151 170M6201 Rated voltage (IEC) 1100V.
