Regulatory Compliant Solutions

When determining the most appropriate solution to meet the lightning and AC power fault

conditions for regulatory requirements, coordination is essential between the SIDACtor

device, fuse, and any series impedance that may be used.

Figure 4.14 through Figure 4.19 show templates in which this coordination is considered for

the most cost effective and reliable solutions available. For exact design criteria and

information regarding the applicable regulatory requirements, refer to the SIDACtor device

and fuse selection criteria in this Section 4, “Regulatory Requirements”, and in Section 5,

“Technical Notes”.

GR 1089 and ITU-T K.20 and K.21

Figure 4.14 and Figure 4.15 show line interface protection circuits to meet GR 1089 surge

immunity requirements without the additional use of series resistance. Use the “C” series

SIDACtor device and F1250T to meet GR 1089 surge immunity requirements. Use the

“A” series SIDACtor device and F0500T to meet ITU-T K.20 and K.21 basic surge immunity

requirements without the additional use of resistance.

The enhanced surge immunity requirements of ITU K.20 and K.21 require the use of “C”

rated SIDACtor devices if no series resistor is used.
