The Schneider Electric A9F05325 is an Acti9 iC60N miniature circuit breaker — a 25 A, D-curve, 3-pole unit rated for both AC and DC networks. Its 36 kA Icu at 12–133 V AC and 20 kA at 220–240 V AC mean it handles high prospective fault currents on distribution boards without needing an upstream current-limiting fuse.
Dual-standard rating and what it means for your panel
This breaker carries both EN/IEC 60898-1 (the MCB standard for household and similar installations) and EN/IEC 60947-2 (the industrial standard for circuit breakers). The 60898-1 rating gives you the 6 kA Icn at 400 V AC — the standard domestic/small-commercial fault level. The 60947-2 rating goes higher: 10 kA Icu at 380–415 V AC and 36 kA at low voltage.
DIN-rail footprint and panel integration
Snaps onto standard DIN rail — 6 x 9 mm pitches wide (54 mm), 91 mm tall, 78.5 mm deep. That 78.5 mm depth is shallow enough to clear most standard gland plates and enclosure backwalls. The toggle and trip indicator are front-facing; you can read the tripped state through the enclosure window without opening the door.
