ComPacT NSX100N 3P3R 40A Micrologic 2.2 Automatic Circuit Breaker

Automatic ComPacT NSX100N 3P3R switch with Micrologic 2.2 control unit, designed to protect electrical circuits in industrial and commercial installations. It offers protection against overload and short circuits through long-term shooting current adjustment (18–40 A) and fixed delay. Compatible with the new generation ComPacT range, it guarantees stability in 50/60 Hz AC networks.
