Coupling impedance (inductance), screw terminals.
- Coarse and fine surge protection for
low-frequency 2-core signalling networks.
- Installation close to protected equipment.
- For protection of analogue measuring lines in
the areas with RF disturbance.
- Coarse and fine surge protection in differential mode (core – core) and common mode (core – PE).
