Figure 3.23 illustrates the use of the P2600SA and P0721CA2 for overvoltage protection
and the F0500T for overcurrent protection in addition to 20 W of series resistance on both
Tip and Ring. The series resistance is required to limit the transient surge currents to within
the surge current rating of the “A” series SIDACtor devices and the F0500T TeleLink fuse.
The illustration of SLIC protection in Figure 3.24 shows Teccor’s Battrax device protecting
Legerity’s (formerly AMD’s) Am79R79 from overvoltages and uses a F1250T to protect
against sustained power cross conditions. The Battrax product was designed specifically to
protect SLICs that cannot withstand potential differences greater than V
