The 10 kA breaking capacity at 380–415 V AC (Icn) and 15 kA Icu at 100–125 V DC tell you it safely interrupts fault currents up to those levels, so it fits panels where the prospective short-circuit current is under those thresholds. Thermal-magnetic trip technology gives you both overload protection (thermal bimetal) and short-circuit protection (magnetic coil) in one package. Clip it onto a 35 mm DIN rail — the 54 mm width (6 x 9 mm pitches) and 77.5 mm depth fit standard distribution boards and sub-panels. The toggle actuator gives clear ON/OFF indication for local status. IP20 finger-safe terminals mean it's meant for enclosed panel use, not washdown environments. The bottom terminals are biconnect/tunnel type, letting you daisy-chain or loop outgoing circuits.","metaTitle":"Schneider Electric A9N3P40DIN Acti9 xC60 MCB, 40 A D Curve,","metaDescription":"Schneider Electric A9N3P40DIN Acti9 xC60 miniature circuit breaker, 40 A rated current, D curve, 10 kA breaking capacity at 415 V AC.
