Schneider C16F32D160 ComPacT NSX160F Trip Unit 3P 160 A MicroLogic 2

The Schneider Electric C16F32D160 is a 3-pole ComPacT NSX160F moulded case circuit breaker rated at 160 A (at 40°C), equipped with a Micrologic 2.2 electronic trip unit and designed for AC power distribution applications. It delivers a rated ultimate short-circuit breaking capacity (Icu) of 36 kA at 380/415 V AC and up to 85 kA at 220/240 V AC per IEC 60947-2. The Micrologic 2.2 unit provides LSoI protection: long-time overload, short-time short-circuit, and instantaneous short-circuit.
