Product details

The A9F45403 is a Schneider Electric Acti9 iC60N miniature circuit breaker — 4 poles, D curve, 3 A rated current. At 3 A, this is sized for a small motor or control transformer branch, not a main feeder.

Dual-standard certification and lifecycle

Tightening torque 2 N·m. Strip length 14 mm. That covers most panel wiring up to a 4 mm² feed for a 3 A branch. The thermal-magnetic trip unit is non-interchangeable — no field-swap of the trip element, so order the exact rating. Padlockable toggle and a trip indicator (red flag visible when tripped) help the field tech confirm isolation before working downstream. Earth-leakage protection requires a separate vigi block — not integrated.

Frequently asked questions

Where can I buy A9F45403 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the breaking capacity of A9F45403?

50 kA Icu at 415 V AC per EN/IEC 60947-2, and 6 kA Icn at 415 V AC per EN/IEC 60898-1. The 50 kA rating is the industrial interrupting capacity — it handles high fault currents without upstream fuses.

What is the D curve magnetic trip threshold?

12 x In ±20 %. For a 3 A breaker, that means magnetic trip between 28.8 A and 43.2 A. This holds motor inrush and transformer magnetizing current without nuisance tripping.

What compliance documentation does Schneider provide for A9F45403?

The part is certified to EN/IEC 60898-1 and EN/IEC 60947-2. It carries IP20 protection (IEC 60529), pollution degree 3, and tropicalisation class 2 (IEC 60068-1). RoHS and REACH declarations are standard for the Acti9 range.
