TLS SerieS TeLecommunicaTionS Power FuSe
170 VDC • Current-Limiting • 1-125 Amperes
Description
Littelfuse TLS Series fuses are designed specifically for the
protection of telecommunications equipment. TLS fuses have
been engineered to operate up to 170 VDC 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.
