Coupling impedance (resistance), screw terminals
- Coarse and fine surge protection for 2-core signalling networks
- Installation close to protected equipment
- For protection of communication interfaces, mainly the RS-485 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 common mode (core – PE)
