The Schneider Electric A9F05432 is a 4-pole Acti9 iC60N miniature circuit breaker rated at 32 A with a D tripping curve. It uses thermal-magnetic trip technology for distribution applications, protecting against overloads and short circuits.
This MCB is certified to both EN/IEC 60898-1 and EN/IEC 60947-2, giving you flexibility in specifying it for residential, commercial, or industrial panels. The breaking capacity hits 36 kA Icu at 12-133 V AC, 20 kA Icu at 220-240 V AC, 10 kA Icu at 380-415 V AC, and 6 kA Icu at 440 V AC per the 60947-2 standard. Under the 60898-1 standard, it is rated for 10 kA Icn at 400 V AC. The high 36 kA rating at lower voltages means it can handle high-fault scenarios common in industrial control panels fed by large transformers.
Snaps onto a DIN rail (mounting support: DIN rail). Occupies 8 x 9 mm pitches (72 mm wide), with a depth of 78.5 mm and height of 91 mm. The double terminals on top and bottom accept 1-35 mm² rigid or 1-25 mm² flexible cable. The IP20 finger-safe front is standard for enclosed panels. Suitable for isolation per both EN/IEC 60898-1 and EN/IEC 60947-2, with a visible contact position indicator and a trip indicator for local signalling.
