The Schneider Electric A9F06416 is an Acti9 iC60H miniature circuit breaker — 4 poles, 16 A rated current, B-curve trip characteristic. Breaking capacity hits 42 kA Icu at 12–133 V AC, 30 kA at 220–240 V, 15 kA at 380–415 V, and 10 kA at 440 V — that's a high-interrupting frame for a 16 A MCB, meaning it can ride through a stiff fault on a large transformer without welding its contacts shut. The 10 kA Icn at 400 V per EN/IEC 60898-1 covers the standard domestic/commercial panel fault level. Dual-certified to EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (household / similar), which gives it a foot in both worlds: the 60947-2 listing carries the higher Icu ratings and isolation suitability, while the 60898-1 listing gives the standard Icn for branch-circuit protection.
IP20 finger-safe front, so it's panel-mount only — no washdown rating.
Carries the usual Schneider declaration of performance and CE marking per the Low Voltage Directive.
