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
lightning 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 used in circuits to obtain compliance with the test
requirements specified in UL 1950/60950 and Bellcor
e GR 1089.
