The C25F34V160 is a Schneider Electric ComPacT NSX earth leakage circuit breaker in the NSX250F frame, rated 160 A at 40 °C with a MicroLogic 4.2 electronic trip unit. It is a 3-pole unit (3P) designed for distribution applications, integrating earth-leakage protection (R) alongside overload (L), short-time short-circuit (So), and instantaneous short-circuit (I) protection. The breaking capacity hits 36 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, and 85 kA Icu at 240 V AC per UL 60947-4-1.
The 160 A trip unit rating at 40 °C sets the continuous current limit for a feeder or main in a distribution panel. The integrated earth-leakage protection (R curve) means this single device covers both overcurrent and ground-fault sensing, saving panel space over a separate RCD. Electronic trip unit (MicroLogic 4.2) gives adjustable long-time pickup and delay, plus fixed short-time and instantaneous settings.
Integration notes
The 105 mm width and 161 mm height fit standard ComPacT NSX panel cutouts. The toggle control and local signalling (flashing green LED for ready, red at 105% Ir overload, orange at 90% Ir) give clear status without opening the panel door.
