| L17T Series Telecommunications Power Fuse 170 VDC I Current Limiting I 70 - 1200 Amperes SPECIFICATIONS Voltage Rating: 170 VDC Interrupting Rating: 100,000 amperes Ampere Range: 70 - 1200 amperes Approvals: UL Recognized under the Components Program (File No: E71611) CSA Recognized under the Component Acceptance Program (File No: LR29862) AMPERE RATINGS 70 90 100 125 150 175 200 225 250 300 350 400 450 500 600 800 900 1000 1100 1200 Example part number (series & amperage): L17T 200 RECOMMENDED FUSE BLOCKS LTFD 6001 and LTFD1200 series Refer to the LTFD series in this catalog section for additional information. Specifically designed for short circuit protection of Telecommunications circuits, the Littelfuse L17T series fuses provide reliable protection of sensitive DC power distribution systems. Constructed with silver plated elements for low I2t and peak let-through, these advanced fuses virtually eliminate equipment damage due to surges and spikes. The L17T series fuse's unique element geometry also provides cooler running temperatures, helping to minimize heat within enclosures. FEATURES I I I I Low I2t Extremely current limiting Low operating temperature 170 VDC rating ORDERING INFORMATION & CROSS REFERENCE Catalog Number L17T 70 L17T 90 L17T 100 L17T 125 L17T 150 L17T 175 L17T 200 L17T 225 L17T 250 L17T 300 L17T 350 L17T 400 L17T 450 L17T 500 L17T 600 L17T 800 L17T 900 L17T 1000 L17T 1100 L17T 1200 Ampere Rating 70 90 100 125 150 175 200 225 250 300 350 400 450 500 600 800 900 1000 1100 1200 Competitor A Part Number TPL-BA TPL-BC TPL-BD TPL-BE TPL-BF TPL-BG TPL-BH TPL-BK TPL-BL TPL-CN TPL-CO TPL-CR TPL-CU TPL-CV TPL-CZ TPL-CZH Competitor B Part Number TGL-BA TGL-BC TGL-BD TGL-BE TGL-BF TGL-BG TGL-BH TGL-BK TGL-BL TGL-CN TGL-CO TGL-CR TGL-CU TGL-CV TGL-CZ TGL-CZH AMPERE RATING DIMENSIONS IN INCHES (mm in parentheses) A 1-5/32 (29.4) B 1-7/8 (47.6) C D E F 7/8 (22.2) 1 (25.4) 1-1/2 (38.1) G 5/16 (7.9) 13/32 (10.3) -- H 3/16 (4.8) 1/4 (6.35) 1/4 (6.35) 2-3/16 2-21/32 1 (55.6) (67.5) (25.4) 3-1/2 (88.9) 4-1/16 (103.12) 1-1/2 (38.1) -- F 70 - 250 G A B C D H E 300 - 800 1-1/4 1-15/16 2-9/16 (31.8) (49.2) (65.1) -- -- 1000 - 1200 1-11/32 (34.0) Fig. 3 Contact Littelfuse for characteristic curves. 75 |
