Product details

The A9F57350 is a 3-pole Acti9 IKQ miniature circuit breaker rated 50 A with a C-curve magnetic trip (5–10 × In). That 10 kA Icn at 415 V AC (EN 60898-1) means it can safely interrupt a fault current up to 10,000 A without welding or arcing over — enough for most commercial and light industrial distribution boards fed by a typical transformer.

DIN-rail fit and wiring

At 54 mm wide (6 x 9 mm pitches), it occupies three modular spaces — standard for a 3P breaker. Bottom terminals accept 1–35 mm² rigid or 1–25 mm² flexible; strip 14 mm and torque to 3.5 N·m. Padlockable toggle for lockout/tagout.

Frequently asked questions

Where can I buy A9F57350 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit a request for quote to confirm current availability and pricing.

What is A9F57350's listed depth (78.5 mm) on this component line?

The depth is 78.5 mm, which is the dimension from the DIN-rail mounting surface to the front of the toggle — standard for Acti9 IKQ breakers.

What is A9F57350's listed range (Acti9) on this component line?

It belongs to the Schneider Electric Acti9 range, the modular DIN-rail miniature circuit breaker family for commercial and light industrial distribution.

What compliance documentation does this brand provide for A9F57350 (RoHS, REACH, UL, IEC)?

The breaker is certified to EN/IEC 60898-1. For RoHS/REACH declarations and any additional compliance documents, request them with your RFQ — they are typically available from the manufacturer upon request.
