Breaking capacity is 25 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, sufficient for most distribution panelboard fault levels in commercial and light industrial installs. The B in the order code (C25B34V160) maps to that 25 kA class at 415 V. 160 A frame with a 160 A trip unit sized for 160 A continuous load. MicroLogic 4.2 provides L, So, I, and R protection curves in one electronic trip unit. Integrated earth-leakage saves a panel slot. For selectivity coordination downstream, the fixed-delay So curve lets you hold for a short interval so branch breakers clear first. Backplate mount, horizontal or vertical. Overvoltage category IV means it's suitable for main distribution boards, not just sub-panels. ## Integration notes Mounts on a backplate — no DIN rail adapter. 105 mm wide, 161 mm high, 86 mm deep. Front connections both upside and downside. The toggle handle is the control interface; the IΔn rotary switch sets the earth-leakage threshold. Five accessory slots available for auxiliary contacts, shunt trips, or motor operators. Electrical durability: 20,000 cycles at 440 V at half rated current, 10,000 cycles at full rated current. Mechanical durability: 20,000 cycles. That's typical for a distribution breaker — not a switching device for frequent motor starts.","metaTitle":"Schneider C25B34V160 ComPacT NSX Earth Leakage Breaker, 160","metaDescription":"Schneider C25B34V160 ComPacT NSX earth leakage circuit breaker, 160 A rated current, 25 kA breaking capacity at 415 V AC.
