ComPacT NSX100N 4P4R 40A Automatic Circuit Breaker

ComPacT NSX100N 4P4R automatic circuit breaker from the new generation range, designed to protect electrical circuits in industrial and commercial installations. Its 4-pole configuration with protection on all conductors (4R) and left-side neutral position makes it suitable for three-phase applications with neutral. Designed for currents above 0.1 A, it offers high breaking capacity under overload and short-circuit conditions.
