Breaking capacity hits 90 kA Icu at 240 V AC and 50 kA at 415 V AC per IEC 60947-2. The integrated earth-leakage protection uses an IΔn rotary switch for OFF mode, with a 20-minute thermal memory before and after tripping. That thermal memory means the breaker remembers the heat profile of a sustained overload — useful on motor or transformer feeders where the same load cycles back on quickly. Lifecycle status is current per the manufacturer. Mounts on a backplate, accepts horizontal or vertical orientation flat against the panel. Width is 105 mm, height 161 mm, depth 86 mm — fits standard panel cutouts for 3-pole molded-case breakers. IP40 enclosure, IK07 impact resistance. Five accessory slots available for shunt trips, auxiliary contacts, or communication modules. ## Protection and ratings Electronic trip unit eliminates thermal drift issues of bimetal types. Electrical durability: 20,000 cycles at 440 V In/2, 10,000 cycles at 440 V In. Mechanical durability 20,000 cycles. Category A utilization. IEC 60947-2 compliance covers the breaking capacities across the voltage range. Local signaling via green flashing LED for ready, red LED at 105% Ir for overload, orange at 90% Ir.","metaTitle":"Schneider Electric C25N34V250 ComPacT NSX Earth Leakage Circ","metaDescription":"Schneider Electric C25N34V250 ComPacT NSX earth leakage circuit breaker, 250 A at 40 °C, 90 kA Icu at 240 V AC, MicroLogic 4.2 trip unit.
