C160N420FM – ComPacT NS1600N Circuit Breaker, 1600A, 4P Fixed, 50kA at 415VAC

The Schneider Electric ComPacT NS1600N (C160N420FM) is a high-performance 4-pole, fixed, manually operated circuit breaker from the new generation ComPacT NS630bN–NS3200 range.
It provides 1600A rated current with a MicroLogic 2.0 electronic trip unit, delivering long-time (overload) and instantaneous (short-circuit) protections in compliance with IEC 60947-2.

With a breaking capacity of 50kA at 415VAC, the NS1600N ensures robust protection for both standard and demanding distribution applications. Its ergonomic toggle, transparent front cover for auxiliary visibility, and compatibility with optional wireless auxiliaries (ZigBee OF/SD contacts) make it versatile, modern, and future-ready.
