What this MCB does on the panel
The 30 kA breaking capacity per IEC 60947-2 tells you it can safely interrupt a fault current up to 30 kA without welding contacts or cascading upstream; that's a serious rating for a 3-module-wide (54 mm) device.
At 45 °C ambient the 13 A rating holds; at 50 °C it derates to 12.68 A, and at 55 °C to 12.34 A.
Mechanical and environmental fit
It is sealable (can be locked in the OFF position for lockout/tagout). Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz, which covers most industrial machinery and conveyor applications. Neutral conductor is not switched (3-pole only), so for a 3-phase + N system you need a separate neutral bus or a 4-pole variant.
