Type RJS
Telecom-Power Cross Protection & Ballast Protection
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 designed to be placed between the line input
and the surge arresting components (mov. gas tube, zenor diode, air gaps, etc.)
These fuses will withstand transient surge currents generated by lighting in
accordance with the attached table.
RJS fuses guard protected circuitry against sustained overload or short circuit
conditions. Such sustained overloads may be generated by accidental contact
between utility cables and phone lines (power line cross).
RJS Fuse are primarily designed for use in telecommunications circuits which
require compliance with the test requirements specified in UL/IEC 1950/60950 and
Telcordia GR 1089, Issue 3
