Technical data105FusesUL class T fuses for branch circuit protection are listed below. Fast acting class T orfaster fuses are recommended in the USA.Check from the fuse time-current curve that the operating time of the fuse isbelow 0.5 seconds for units of frame sizes R2 to R4 and 0.1 seconds for unitsof frame sizes R5 and R6. The operating time depends on the supply networkimpedance and the cross-sectional area and length of the supply cable. The short-circuit current can be calculated as shown in section Frame sizes R5 and R6 onpage 96.Note 1: See also Planning the electrical installation: Thermal overload and short-circuit protection.Note 2: In multicable installations, install only one fuse per phase (not one fuse per conductor).Note 3: Larger fuses than the recommended ones must not be used.Note 4: Fuses from other manufacturers can be used if they meet the ratings and the melting curve ofthe fuse does not exceed the melting curve of the fuse mentioned in the table.ACS800-U4typeFrame size InputcurrentFuseA A V Manufacturer Type UL classThree-phase supply voltage 208 V, 220 V, 230 V or 240 V-0002-2 R2 5.2 10 600 Bussmann JJS-10 T-0003-2 R2 6.5 10 600 Bussmann JJS-10 T-0004-2 R2 9.2 15 600 Bussmann JJS-15 T-0006-2 R3 18 25 600 Bussmann JJS-25 T-0009-2 R3 24 30 600 Bussmann JJS-30 T-0011-2 R3 31 40 600 Bussmann JJS-40 T-0016-2 R4 38 50 600 Bussmann JJS-50 T-0020-2 R4 49 70 600 Bussmann JJS-70 T-0025-2 R5 64 90 600 Bussmann JJS-90 T-0030-2 R5 75 100 600 Bussmann JJS-100 T-0040-2 R5 102 125 600 Bussmann JJS-125 T-0050-2 R6 126 175 600 Bussmann JJS-175 T-0060-2 R6 153 200 600 Bussmann JJS-200 T-0070-2 R6 190 250 600 Bussmann JJS-250 TThree-phase supply voltage 380 V, 400 V, 415 V, 440 V, 460 V or 480 V-0004-5 R2 4.1 10 600 Bussmann JJS-10 T-0005-5 R2 5.4 10 600 Bussmann JJS-10 T-0006-5 R2 6.9 10 600 Bussmann JJS-10 T-0009-5 R2 9.8 15 600 Bussmann JJS-15 T-0011-5 R2 13 20 600 Bussmann JJS-20 T-0016-5 R3 18 25 600 Bussmann JJS-25 T-0020-5 R3 24 35 600 Bussmann JJS-35 T-0025-5 R3 31 40 600 Bussmann JJS-40 T-0030-5 R4 40 50 600 Bussmann JJS-50 T-0045-5 R4 54 70 600 Bussmann JJS-70 T-0050-5 R5 63 80 600 Bussmann JJS-80 T-0060-5 R5 77 100 600 Bussmann JJS-100 T-0070-5 R5 94 125 600 Bussmann JJS-125 T-0105-5 R5 138 150 600 Bussmann JJS-150 T-0100-5 R6 121 150 600 Bussmann JJS-150 T-0120-5 R6 155 200 600 Bussmann JJS-200 T-0140-5 R6 179 225 600 Bussmann JJS-225 T-0205-5 R6 243 350 600 Bussmann JJS-350 TPhone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
