Secondary Protectors
Secondary protectors are adjunct devices (they can be either stand alone units or
integrated into strip protectors and UPS
’
) used to enhance the protection level of
customer premise equipment (CPE). Due to the inadequate level of protection being
designed into CPE, secondary protectors are often required to help prevent premature
failure of equipment that is exposed to environmental hazards (Figure 3-31).
Protection Requirements
Secondary protectors should be able to withstand over-voltages that can exceed 800V
and surge currents of up to 100A. In Figure 3-32, the SIDACtor was chosen because
the associated peak pulse current (I
PP
) is great enough to withstand the lightning
immunity tests of FCC Part 68 without the additional use of series line impedance.
Likewise, the fuse in Figure 3-32 was chosen because the amps
2
time (I
2
t) rating is
large enough to withstand the lightning immunity tests of FCC Part 68, but small
enough to pass UL power cross conditions.
Applicable Regulatory Requirements
UL 497A
Secondary Protection Reference Circuit
Figure 3-32 is an example of an interface design for a secondary protector. The
P3203AB SIDACtor is used because the peak off-state voltage (V
DRM
) is greater than
the potential of a Type B ringer signal superimposed on the POTS (plain old telephone
service) battery.

Coordination between the station protector and the secondary protector occurs due to
the line impedance between the two devices (Figure 3-31). The line impedance helps
ensure that the primary protector will begin to conduct while the secondary protector
limits any of the let through voltage to within the V
S
rating of the SIDACtor.
