Breaking capacity & derating
Rated breaking capacity: 15 kA per EN 60898, 30 kA per IEC 60947-2. That 30 kA figure matters if the upstream transformer can dump that much fault current — it means the MCB clears a bolted fault without rupturing. Thermal derating is published: 10 A at 35 °C drops to 8.04 A at 60 °C.
Installation depth 70 mm. IP20 with conductors connected — fine for enclosed panels, not for washdown. Halogen-free and silicon-free construction, sealable with a lead seal if your site requires tamper evidence.
