Product overview and key ratings
The Schneider Electric A9F57110 is a 1-pole Acti9 IKQ miniature circuit breaker (MCB) rated 10 A with a C-curve characteristic, designed for AC networks at 50/60 Hz. Its 10 kA Icn breaking capacity at 240 V AC, certified to EN 60898-1, means it can safely interrupt fault currents up to 10,000 A without welding its contacts — a figure that governs selectivity coordination in a distribution board.
Compliance and lifecycle status
For compliance documentation, the Acti9 range is manufactured under Schneider Electric's ISO 9001 and ISO 14001 certified processes. RoHS and REACH declarations of conformity are standard for this product family; the specific declaration for order code A9F57110 is available on request with the RFQ.
Mounting and integration details
Its 18 mm width (2 x 9 mm pitches) occupies a single module position in a distribution board, and the 78.5 mm depth fits standard enclosure depths without protruding past the gland plate. The toggle control provides visual contact position indication, and a trip indicator flag confirms the breaker has operated on fault. Padlockable for lockout/tagout procedures. IP20 rated — suitable for installation inside a distribution board or enclosure, not for wet or washdown environments.
Durability and environmental range
Rated for 10,000 electrical cycles and 20,000 mechanical cycles — figures that reflect the breaker's endurance under normal switching and fault-clearing duty. These limits cover most indoor panel environments, including unheated warehouses and rooftop enclosures in temperate climates.
