RJS Series
RoHS 2
Compliant
Description
RJS Fuses are primarily intended for use in telecommunication circuit applications
requiring low current protection
with high surge tolerance.
They are typically used to
replace heat coil type devices. They are de
signed to be placed
between the line input
and the surge arresting components (mov. gas tube, zenor diode, air gaps, etc
.
)
T
hese fuses will withstand transient surge currents generated by lighting in
accordance wi
th the attached table
.
RJS fuses guard protected circui
try
against sustained overload or short cir
cuit
conditions. Such sustained
overl
oads may be generated by accidental
contact
betw
een utility
cables and phone lines (power line cross
).
RJS Fuse are
primarily designed for use in telecommunications circu
its which
require compliance with the test
requirements specified in UL
/
IEC 1950/60950 and
Telcordia GR 1089, Issue 3
