Product details

It protects a single pole plus neutral (1P+N) in 50 Hz AC distribution networks, using a thermal-magnetic trip unit that responds to overloads and short-circuits.

Breaking capacity and dual-standard certification

This breaker carries two breaking capacity ratings under separate standards. At 230 V AC, the Icn (rated short-circuit capacity per EN/IEC 60898-1) is 6000 A — the value used for domestic and similar installations. Under IEC 60947-2, the Icu (ultimate breaking capacity) reaches 10 kA at 230...240 V AC, which is the figure an industrial panel designer references for SCCR coordination. Dual certification means the same unit satisfies both a residential distribution board spec and a control-panel short-circuit rating, simplifying BOM consolidation.

The 18 mm width per pole — two 9 mm pitches — keeps the 1P+N assembly at 18 mm total, fitting standard distribution board spacing.

Frequently asked questions

Where can I buy A9N21364 and how do I get a price?

The A9N21364 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 delivery estimate.

What is A9N21364's breaking capacity at 230 V?

The Icn (rated short-circuit capacity per EN/IEC 60898-1) is 6000 A at 230 V AC. Under IEC 60947-2, the Icu (ultimate breaking capacity) is 10 kA at 230...240 V AC.

What standards does the A9N21364 comply with?

It is dual-certified to EN/IEC 60898-1 and EN/IEC 60947-2, covering both domestic/residential and industrial/panel applications. It also carries NF quality labeling and meets pollution degree 3 per IEC 60947-2 and tropicalisation class 2 per IEC 60068-1.
