The 10 kA breaking capacity (per EN 60898 and IEC 60947-2) tells you it can safely interrupt a fault up to 10,000 A at 400 V AC without welding its contacts or cascading upstream. That's the standard for most sub-distribution boards in European-style installations. Rated current derates with ambient temperature: 1.6 A at 30 °C, 1.54 A at 40 °C, 1.5 A at 45 °C, 1.43 A at 55 °C.
Occupies one modular width unit (18 mm wide). Mounts in any position — no derating for orientation. The IP20 rating applies with conductors connected, which is the norm for enclosed distribution boards. Sealable and halogen-free, silicon-free construction — suitable for clean-room or food-production zones where outgassing contaminants are a concern.
