Littelfuse TLS Series The TLS series fuses are specifically designed 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 of 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. Mounting configurations include cartridge, vertical, leaded, bolt-in, or solder type. These fuses are also RoHS compliant.
