Features and benefits:

• MicroLogic Vigi 4.2 electronic unit delivers overload (L), short-time delay (So), instantaneous (I), and residual current (R) protection in a single integrated device.
• Adjustable earth leakage sensitivity from 30 mA to 5 A with selectable time delays from 0 ms to 1 s enables precise coordination in tiered distribution networks.
• Class A residual current protection covers both AC and pulsating DC fault currents.
• Thermal memory active for 20 minutes before and after tripping prevents premature reconnection of overloaded circuits.
• LED local indication signals device ready (green), 90% Ir overload warning (orange), and 105% Ir overload alarm (red).

Applications:

• Main and sub-distribution boards in commercial and industrial buildings requiring combined overcurrent and earth fault protection.
• Protection of large loads, motors, and transformers in industrial switchboards and process control panels.
• Installations requiring Class A residual current protection with selective coordination against downstream devices.
• High-current feeder circuits where adjustable trip thresholds and earth leakage sensitivity are essential.

Compliant with EN/IEC 60947-2. Part of the Schneider Electric ComPacT NSX new generation range.
