Schneider C6344V570 MicroLogic Vigi 4.3 Trip Unit

The C6344V570 Schneider is a MicroLogic Vigi 4.3 electronic trip unit designed for reliable protection in low-voltage power distribution systems. Specifically engineered for integration with ComPacT NSX630 circuit breakers, this unit supports 4-pole configurations and is rated for 570 A at 40 °C.

It offers essential protection functions, including long-time (L), short-time (S), instantaneous (I), and earth-leakage (R) protection, with adjustable settings to accommodate various applications. The integrated earth leakage protection provides early fault detection with tripping functionality, enhancing system safety. Compliant with IEC 60947-2 standards, it ensures reliable performance in industrial and commercial environments.
