Telecommunications Fuses TLS Series Compact Current Limiting Telecommunications Fuse Description Littelfuse TLS series fuses are designed specifically for the protection of telecommunications equipment. TLS fuses have been engineered to operate up to 170 V dc to provide current-limiting short-circuit protection for cables and components found in the dc power distribution circuits of telecommunications systems. The compact design and multiple mounting configurations of the TLS series allow it to be used in a variety of applications. Features & Benefits FEATURES BENEFITS Current-limiting Provides quick response to short circuit events Multiple mounting configurations Suitable for a variety of applications Applications Telecommunication equipment protection Short-circuit current protection Specifications Voltage Rating 170 V dc Ampere Range 1 125 A Interrupting Rating 100 kA Applicable Standards UL 248-1 IEC-60269-4 Material Body: glass melamine Caps: silver-plated brass Environmental RoHS Compliant, lead (Pb) free Country of Origin Mexico Certification & Compliance cURus File: E71611 CE EU DOC-TLS 210921 0 TUV Cert No: R 50494871 (70 kA IR) Littelfuse.com/TLS 2021 Littelfuse, Inc. 1 Rev: 101221Telecommunications Fuses TLS Series Accessories LFTD series disconnect switches LFT30060 fuse holder for TLS series cartridge style fuse Contact factory for more information.
