TELECOMMUNICATIONS SPECIAL PURPOSE FUSES

Ferraz Shawmut telecommunications fuses are specially
designed for the protection of telecommunications
equipment which includes telephone switching
equipment, rectifiers, distribution switching panels,
battery back-up modules, power supplies and
switching sub-stations.

The telecom fuses are available from 1 to 800 amperes
rated at 170VDC with an interrupting rating of 100,000
amps to fulfill your circuit protection needs. The telecom
fuses have high current limiting capabilities to provide
a better degree of circuit protection to traditional tele­communications equipment. These fuses consist of a
blue and white label for easy identification of their DC
voltage capability.
