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
