The Schneider Electric A9F05470 is an Acti9 iC60 miniature circuit-breaker (MCB) rated 0.5 A with a D tripping curve, 4 poles, and a 50 kA breaking capacity at 415 V AC. At 0.5 A it's a low-current branch feeder, not a main; think control transformer secondary or a small pump motor.
Mounting and integration — DIN rail, 4-pole, 8 modules wide
Snaps onto standard DIN rail per. At 72 mm wide (8 x 9 mm pitches), it occupies eight module spaces in the enclosure — plan your rail layout accordingly. IP20 rated — fine for enclosed panels, not for washdown zones.
Standards and compliance — dual-rated to EN/IEC 60898-1 and 60947-2
Dual-certified to both EN/IEC 60898-1 (the household / similar installation standard) and EN/IEC 60947-2 (the industrial standard for low-voltage switchgear). That means it's accepted in residential, commercial, and industrial distribution boards — the 60947-2 rating gives you the higher Icu breaking capacities (50 kA at 415 V) and the pollution degree 3 rating for harsher environments. Overvoltage category IV suits it for the main distribution point.
