The Schneider Electric A9F07302 is a 3-pole Acti9 iC60H miniature circuit breaker with a C-curve, rated at 2 A. It is a thermal-magnetic trip unit designed for distribution applications in AC or DC networks.
This breaker carries a 70 kA Icu at 220...240 V AC and at 380...415 V AC per EN/IEC 60947-2. At 440 V AC the Icu drops to 50 kA, and under the EN/IEC 60898-1 standard its Icn (rated short-circuit capacity) is 10 kA at 400 V AC. The Icn of 10 kA is the value used for domestic/similar installations. It is also rated for isolation — you can use it as a disconnecting means, verified by the contact position indicator that shows when the contacts are open.
Mounting and integration — DIN rail fit
The 3-pole body takes 6 x 9 mm pitches, so the occupied width is 54 mm. Depth is 78.5 mm, height 91 mm. IP20 finger-safe terminals — fine inside a closed panel, not for wet locations. The white colour is standard for the Acti9 range.
Lifecycle stage is current — this is an active, in-production part from Schneider Electric's Acti9 family. Pollution degree 3 means it is rated for the conductive environment inside a typical industrial panel. Overvoltage category IV confirms it can be used at the service entrance or main distribution board. Earth-leakage protection is a separate block — this MCB alone does not provide GFCI; pair it with a Vigic iC60 if needed.
