Product details

The Schneider Electric A9F05270 is a miniature circuit-breaker from the Acti9 iC60 series, rated 0.5 A with a D trip curve and 2 poles. It protects distribution circuits against overloads and short-circuits using a thermal-magnetic mechanism, and it's rated for isolation per EN/IEC 60898-1 and EN/IEC 60947-2.

Mounts on a DIN rail, 36 mm wide (2 x 18 mm modular pitches), 91 mm tall, 78.5 mm deep. That's a standard 2-module footprint — it occupies two 9 mm pitches on the rail. The IP20 finger-safe terminals accept double conductors: 1–25 mm² rigid or 1–16 mm² flexible. The white housing with toggle and trip indicator gives a clear visual on faulted breakers during a walk-down.

Frequently asked questions

What is the breaking capacity of A9F05270?

The A9F05270 has a 50 kA Icu at 220-240 V AC (per IEC 60947-2) and a 10 kA Icn at 400 V AC (per IEC 60898-1). The 50 kA rating means it can safely clear a fault current up to 50,000 amps at typical single-phase supply voltages.

What is the closest alternative to A9F05270 in the same family?

Within the Acti9 iC60 range, the closest alternative would be a different current rating or curve code — the mechanical footprint, breaking capacity, and terminal specs are shared across the series. For a 0.5 A D-curve 2P breaker, no direct pin-compatible substitute exists outside this order code; verify the specific rating against your load before substituting.

What compliance documentation does Schneider provide for A9F05270?

The A9F05270 is certified to EN/IEC 60947-2 and EN/IEC 60898-1, with tropicalisation class 2 per IEC 60068-1. Schneider provides the usual compliance pack (RoHS, REACH, CE, UKCA) on request through the distributor.

Where can I buy A9F05270 and how is it quoted?

The A9F05270 is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commercial offer.
