The D curve means magnetic tripping occurs at 12 x In ±20 % — that is 72 A instantaneous, ±14.4 A. The 36 kA Icu at 12-133 V AC (EN/IEC 60947-2) is the maximum short-circuit current it can safely interrupt once; at 220-240 V AC that drops to 20 kA, and at 380-415 V AC to 10 kA. For a 400 V distribution panel the Icn per EN/IEC 60898-1 is 6 kA at 400 V — that is the rated short-circuit capacity for household-type use. If your fault level at the panel exceeds 6 kA at 400 V, you need to coordinate upstream or use the higher Icu figures under the industrial standard. Snaps onto DIN rail (mounting support per). Occupies 6 x 9 mm pitches — 54 mm wide. Overvoltage category IV means it can be installed at the service entrance or main distribution board, not just sub-panels. Dual-certified to both EN/IEC 60898-1 (household-type MCB) and EN/IEC 60947-2 (industrial circuit-breaker). The industrial standard gives you the higher Icu ratings and category A utilization (not current-limiting for selectivity in the same way as category B). Suitability for isolation is confirmed under both standards — the contact position indicator shows open/closed state, and the trip indicator flags a thermal or magnetic trip.","metaTitle":"Schneider Electric A9F05306 Acti9 iC60N MCB, 6 A D Curve, 3P","metaDescription":"Schneider Electric A9F05306 Acti9 iC60N miniature circuit breaker, 6 A rated current, D curve, 3 poles, 36 kA Icu at 12-133 V AC.
