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).
