Its headline rating is a 36 kA breaking capacity (Icu) at 12–133 V AC, which drops to 20 kA at 220–240 V and 10 kA at 380–415 V — the figure that governs your SCCR coordination downstream. ## DIN-rail integration and terminal work Terminals accept 1–35 mm² rigid or 1–25 mm² flexible copper; strip 14 mm and torque to 3.5 N.m. The removable comb busbar is installed from the factory, so you can daisy-chain phases across adjacent breakers without extra wiring. IP20 B finger-safe protection on the front face; the back and terminals are live when busbar is energized — standard for this class. ## Standards compliance and approvals Dual-rated to EN/IEC 60898-1 (for household and similar installations) and EN/IEC 60947-2 (for industrial applications). Suitability for isolation is confirmed under both standards. Tropicalisation class 2 per EN/IEC 60068-2-78 (95% RH at 55 °C) covers humid environments without derating.","metaTitle":"Schneider Electric A9F68240 Acti9 iT60 MCB, 40 A, C Curve, 2","metaDescription":"Schneider Electric A9F68240 Acti9 iT60 miniature circuit breaker, 40 A, C curve, 2-pole, 36 kA breaking capacity.
