Description
Technical data
- Class I / (B+C)
- Connections: 3+0, 4+0, 3+1
- Surge discharge ratings Iimp: from 12,5 kA to 25 kA (10/350)/pole
- Housing: compact
- The (3 + 0) range is intended to be used on TNC three phase networks with PEN conductor
- The (4 + 0) range is intended to be used on TNS three phase networks with separate N and PE conductors
- The (3 + 1) range is intended to be used on TT three phase networks where N and PE galvanic isolation is required
