MJS

Fuses are primarily intended for

use in telecommunication circuit applica-

tions 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.

MJS

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).

MJS

Fuses are used in circuits to obtain compliance with the test

requirements specified in UL 1459 and Bellcore 1089.
