Protects measuring transformers; lightning and surge voltage protector for 1A respectively 5A cores in current transformers.
- Remote signaling contact: closer
- Protects measuring transformers
- Very high impulse and AC current resistivity
- No blow-out vents, thus, not requiring any safety clearance to other installations
- High insulation resistance Risol: ? 10 G?
- Very long service life
- Lightning impulse current discharge capacity 100 kA (10/350 µs)
- EAC certification
