Schneider C6342D630 ComPacT NSX630 Trip Unit 4P 630 A MicroLogic 2

The Schneider Electric C6342D630 is a MicroLogic 2.3 electronic trip unit for the ComPacT NSX630 4-pole circuit breaker, rated 630 A at 40°C. Operating on AC networks up to 690 V AC at 50/60 Hz, it delivers LSoI protection - long-time overload, fixed-delay short-time, and instantaneous short-circuit protection.

Features and benefits:

• LSoI protection covers long-time overload, short-time short-circuit with fixed delay, and instantaneous trip in a single electronic unit.
• Ir (250...630 A) and Isd (1.5...10 x Ir) are each independently adjustable across 9 settings for precise protection coordination.
• Three neutral protection modes (0.5 x Ir, 1 x Ir, or unprotected) adapt to different 4-pole network configurations.
• Thermal memory retains circuit thermal state for 20 minutes after tripping, preventing premature re-energisation of overloaded circuits.
• Three-level LED indication shows device status: blinking green (ready), orange (90% Ir pre-alarm), red (105% Ir trip).

Applications:

• Power distribution switchboards in industrial facilities and commercial buildings
• Protection of main feeders in low-voltage assemblies operating up to 690 V AC
• Selective protection coordination in tiered LV distribution systems
• Panel building for energy distribution in utilities, data centres, and manufacturing plants

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