Coupling impedance (R – resistance).

Coarse and fine surge protection for 2-core signalling lines.
Installation close to protected equipment.
For protection of communication interfaces of I<(>&<)>C, electronic security and fire detection systems, etc. (mainly for RS-485 interfaces) against impact of surge voltage.
Coarse and fine surge protection in differential mode (core – core) and common mode (core – PE).
