Product details

What this MCB covers

The 6 kA Icn (EN/IEC 60898-1) handles most domestic fault levels; the 10 kA Icu (IEC 60947-2) gives headroom for industrial sub-distribution where higher prospective fault current is expected.

Clip-on mounting to standard DIN rail, 54 mm wide (6 x 9 mm pitches) — occupies three modular spaces plus one for the neutral. Depth 78 mm, height 81 mm. Wire strip length 13 mm. IP20 finger-safe front; pollution degree 3 rated, so suitable for panels without sealed enclosures.

Listed as current production. No official successor — this is the active DT40N variant for the Prodis range.

Frequently asked questions

Where can I buy A9N21410 and how do I get a price?

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 estimate.

What is A9N21410's breaking capacity and what standards does it meet?

The MCB carries a 6 kA Icn at 400 V AC per EN/IEC 60898-1 and a 10 kA Icu at 400–415 V AC per IEC 60947-2. The dual rating means it meets both domestic (60898-1) and industrial (60947-2) application standards, giving flexibility in panel design.

What compliance documentation does this brand provide for A9N21410?

The part carries NF quality label certification and conforms to EN/IEC 60898-1 and EN/IEC 60947-2. Tropicalisation level 2 per IEC 60068-1 and limitation class 3 per EN/IEC 60898-1 are specified. Standard compliance documentation (declaration of conformity, CE) is provided with the product.
