Product details

The D curve (magnetic tripping limit 10–14 × In) means it tolerates the high inrush of motor, transformer, or welding loads without nuisance tripping — the breaker holds through the start-up surge and clears only on a sustained overload or hard fault. Clip-on mounting to DIN rail (IP20 finger-safe enclosure) makes it a straight swap into a standard panel layout. Breaking capacity is dual-rated: 6 kA Icn at 400 V AC per EN/IEC 60898-1 for general distribution, and 10 kA Icu at 400–415 V AC per IEC 60947-2 for industrial circuits with higher prospective fault current.

Compliance and approvals

Dual-certified to EN/IEC 60898-1 and EN/IEC 60947-2, so it qualifies for both residential/commercial distribution boards (60898-1) and industrial switchgear assemblies (60947-2).

Frequently asked questions

What is the breaking capacity of A9N21419?

6 kA Icn at 400 V AC per EN/IEC 60898-1 and 10 kA Icu at 400–415 V AC per IEC 60947-2.

What does the D curve mean on this breaker?

The D curve has a magnetic tripping limit of 10–14 × In, so it handles high inrush currents from motors, transformers, and welding equipment without nuisance tripping.

Where can I buy A9N21419?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
