It is a 3P+N device rated at 10 A with a B tripping curve. The breaking capacity is 10 kA Icu at 400 V AC per IEC 60947-2, and 6000 A Icn at 400 V AC per IEC 60898-1. That dual rating means this breaker is certified for both the industrial standard (60947-2) and the domestic/light-commercial standard (60898-1), giving it a wider acceptance in panel specs that call for either. The limitation class is 3 per EN/IEC 60898-1, which means it limits let-through energy enough to protect downstream equipment in most fault scenarios. The thermal-magnetic trip unit handles the overload (thermal) and short-circuit (magnetic) protection. The magnetic trip is factory-set to 4 x In ±20% per IEC 60947-2, and the B-curve window of 3 to 5 x In per IEC 60898-1.
Clip-on mounting onto a DIN rail. The 3P+N breaker occupies 6 module pitches of 9 mm each, so 54 mm total width. Strip length is 14 mm. The toggle control provides ON/OFF indication plus a trip indicator. Contact position indicator is present, so you can visually confirm the state of the contacts.
The breaker is certified to EN/IEC 60898-1 and EN/IEC 60947-2. The dual certification is a practical advantage: it satisfies both the domestic MCB standard and the industrial standard for circuit-breakers, so the same part can be specified in a panel that must meet either or both. The suitability for isolation (IEC 60947-2) adds another layer of utility — the breaker can serve as a disconnecting means without requiring a separate isolator. Operating altitude is rated to 2000 m. Relative humidity tolerance is 95% at 55 °C. The electrical and mechanical durability are both rated at 20,000 cycles. Earth-leakage protection is handled by a separate block (not integrated), so if you need RCD protection, you pair this with a compatible Acti9 Vigi module.
