Square Body Semiconductor Fuses 700/1300 VAC ■ Very Fast-Acting ■ 63 – 2500 Amperes SPECIFICATIONS Voltage Rating: AC: 700 Volts (LA070) 1300 Volts (LA130) DC: Contact factory Interrupting Rating: AC: 200,000 Amperes (LA070) 100,000 Amperes (LA130) DC: Contact factory Ampere Range: 63 – 2500 Amperes Approvals: UL Recognized Component NEW ORDERING INFORMATION Littelfuse’s North American style square body semiconductor fuses provide maximum flexibility in equipment design and ultimate protection for today’s power conversion equipment. Available in different body sizes and multiple mounting styles, the broad range of ampere ratings allows great flexibility in equipment design. Engineered to provide state-of-the-art protection for SCR’s, diodes, thyristors, GTO’s, and IGBT devices, Littelfuse square body fuses have pure die-cut elements embedded in solidified sand to control arcing and lower I2t. All fuses are also equipped with a blown fuse trip indicator. LA 070 URD 31 LI 350 Littelfuse Voltage 070=700V 130=1300V Class Size 700V 1300V 30 70 31 71 32 72 33 73 FEATURES ■ ■ ■ ■ ■ Choice of mounting styles provides a wide choice for equipment design. Broad range of ampere ratings in a given body size for design flexibility. Very low I2t minimizes damage to protected components. Superior cycling ability for long, reliable life on high cyclic loading. Extremely fast-acting and current limiting for improved protection to equipment. APPLICATIONS Protection of rectifiers, inverters, DC drives, UPS systems, reduced voltage motor starters, and other equipment in globally accepter applications. 100 Mounting Types Straight-blade KI Straight-blade LI Flat-type, one hole TTI Amp Rating LI LLI TTI Square Body Semiconductor Fuses 700/1300 VAC ■ Very Fast-Acting ■ 63 – 2500 Amperes 700 Volt North American Style Ratings and Application Data Body Size 30 31 32 33 Amp Rating Rated Voltage Melting I23t 2 (A S x 10 ) Total I2t @ Rated Voltage 2 3 (A S x 10 ) **Watts Loss @ Rated Current (W) Long Blade Catalog No. Type LI Short Blade Catalog No. Type KI Tapped Terminal Catalog No. Type TTI 63 80 100 125 160 200 250 315 350 400 450 500 550 200 250 315 350 400 450 500 550 630 700 800 400 450 500 550 630 700 800 900 1000 1100 1250 1400 1600 1800 500 550 630 700 800 900 1000 1100 1250 1400 1600 1800 2000 2250 2500 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 700 650 600 550 550 500 700 700 700 700 700 700 700 700 700 700 650 650 600 550 500 0.2 0.33 0.47 0.85 1.6 3 5.8 12 15.5 23 26 41 52 2.5 4.7 7.5 10.5 19 26.5 37 52 75 95 140 15 22 28 37 54 76 115 170 240 270 410 555 870 1050 19 27 40 55 95 135 170 240 350 480 555 720 950 1250 1870 1.2 1.9 2.7 4.9 9.2 16.7 32.4 67 86 130 165 264 330 14.6 27 43 59 110 150 210 300 421 530 880 86 124 157 211 302 432 648 972 1350 1620 2100 2600 4000 4400 108 151 227 324 529 760 970 1360 2000 2700 3250 4330 5000 5900 7600 14 19 26 30 37 42/43 48/50 53/55 57/60 60/65 80/88 80/88 80/90 45 52 65 67 68 70 70/72 70/75 75/85 85/95 105/120 72/75 77/80 85/90 90/95 95/105 100/110 110/120 110/125 115/135 140/165 150/180 160/190 165/195 195/330 105 105/110 110/120 115/125 120/130 120/135 135/155 135/160 150/180 160/200 210/240 225/260 250/290 280/330 280/330 LA070URD30LI0063 LA070URD30LI0080 LA070URD30LI0100 LA070URD30LI0125 LA070URD30LI0160 LA070URD30LI0200 LA070URD30LI0250 LA070URD30LI0315 LA070URD30LI0350 LA070URD30LI0400 LA070URD30LI0450 LA070URD30LI0500 LA070URD30LI0550 LA070URD31LI0200 LA070URD31LI0250 LA070URD31LI0315 LA070URD31LI0350 LA070URD31LI0400 LA070URD31LI0450 LA070URD31LI0500 LA070URD31LI0550 LA070URD31LI0630 LA070URD31LI0700 LA070URD31LI0800 LA070URD32LI0400 LA070URD32LI0450 LA070URD32LI0500 LA070URD32LI0550 LA070URD32LI0630 LA070URD32LI0700 LA070URD32LI0800 LA070URD32LI0900 LA070URD32LI1000 LA065URD32LI1100 LA060URD32LI1250 LA055URD32LI1400 LA055URD32LI1600 LA050URD32LI1800 LA070URD33LI0500 LA070URD33LI0550 LA070URD33LI0630 LA070URD33LI0700 LA070URD33LI0800 LA070URD33LI0900 LA070URD33LI1000 LA070URD33LI1100 LA070URD33LI1250 LA070URD33LI1400 LA065URD33LI1600 LA065URD33LI1800 LA060URD33LI2000 LA050URD33LI2250 LA050URD33LI2500 LA070URD30KI0063 LA070URD30KI0080 LA070URD30KI0100 LA070URD30KI0125 LA070URD30KI0160 LA070URD30KI0200 LA070URD30KI0250 LA070URD30KI0315 LA070URD30KI0350 LA070URD30KI0400 LA070URD30KI0450 LA070URD30KI0500 LA070URD30KI0550 LA070URD31KI0200 LA070URD31KI0250 LA070URD31KI0315 LA070URD31KI0350 LA070URD31KI0400 LA070URD31KI0450 LA070URD31KI0500 LA070URD31KI0550 LA070URD31KI0630 LA070URD31KI0700 LA070URD31KI0800 LA070URD32KI0400 LA070URD32KI0450 LA070URD32KI0500 LA070URD32KI0550 LA070URD32KI0630 LA070URD32KI0700 LA070URD32KI0800 LA070URD32KI0900 LA070URD32KI1000 LA070URD33KI0500 LA070URD33KI0550 LA070URD33KI0630 LA070URD33KI0700 LA070URD33KI0800 LA070URD33KI0900 LA070URD33KI1000 LA070URD33KI1100 LA070URD33KI1250 LA070URD33KI1400 - LA070URD30TTI0063 LA070URD30TTI0080 LA070URD30TTI0100 LA070URD30TTI0125 LA070URD30TTI0160 LA070URD30TTI0200 LA070URD30TTI0250 LA070URD30TTI0315 LA070URD30TTI0350 LA070URD30TTI0400 LA070URD30TTI0450 LA070URD30TTI0500 LA070URD30TTI0550 LA070URD31TTI0200 LA070URD31TTI0250 LA070URD31TTI0315 LA070URD31TTI0350 LA070URD31TTI0400 LA070URD31TTI0450 LA070URD31TTI0500 LA070URD31TTI0550 LA070URD31TTI0630 LA070URD31TTI0700 LA070URD31TTI0800 LA070URD32TTI0400 LA070URD32TTI0450 LA070URD32TTI0500 LA070URD32TTI0550 LA070URD32TTI0630 LA070URD32TTI0700 LA070URD32TTI0800 LA070URD32TTI0900 LA070URD32TTI1000 LA065URD32TTI1100 LA060URD32TTI1250 LA055URD32TTI1400 LA055URD32TTI1600 LA050URD32TTI1800 LA070URD33TTI0500 LA070URD33TTI0550 LA070URD33TTI0630 LA070URD33TTI0700 LA070URD33TTI0800 LA070URD33TTI0900 LA070URD33TTI1000 LA070URD33TTI1100 LA070URD33TTI1250 LA070URD33TTI1400 LA065URD33TTI1600 LA065URD33TTI1800 LA060URD33TTI2000 LA055URD33TTI2250 LA050URD33TTI2500 ** Watts loss data is published for both blade and tapped style mounting configurations.
