Coupling impedance (resistance), screwless terminals
- Coarse and fine surge protection for 2-core signalling networks
- Installation close to protected equipment
- For protection of communication interfaces and measuring lines of I&C, electronic security and fire detection systems, etc. against impact of surge voltage
- Coarse and fine surge protection in differential mode (core – core) and coarse protection in common mode (core – PE)
