Breaking capacity is 6 kA Icn at 230 V AC per EN/IEC 60898-1, and 10 kA Icu at 230–240 V AC per IEC 60947-2 — enough for most residential and light commercial service-entrance panels where the upstream transformer impedance limits fault current. Curve C means the magnetic trip operates at 5 to 10 times rated current (10–20 A for this 2 A unit). For high-inrush loads (transformers, large motors) a D curve would be needed. Thermal-magnetic trip technology combines a bimetal strip for overload protection and a solenoid for short-circuit. The 20,000-cycle electrical and mechanical endurance matches the duty expected in a distribution board that sees occasional switching, not daily load-break. Pollution degree 3 (IEC 60947-2) and overvoltage category IV mean the breaker is rated for the harsh electrical environment of a main distribution panel — not just downstream sub-circuits. Tropicalisation class 2 (IEC 60068-1) adds humidity tolerance up to 95% RH at 55 °C.","metaTitle":"Schneider Electric A9N21361 DT40N MCB, 2 A, Curve C, 1P+N","metaDescription":"Schneider Electric A9N21361 DT40N MCB, 2 A rated current, curve C, 1P+N, 6 kA breaking capacity per EN/IEC 60898-1.
