The breaking capacity is 10 kA per EN 60898 and 20 kA per IEC 60947-2 — the higher IEC figure gives selectivity headroom when coordinating with an upstream 25 kA or 36 kA device. The part is marked for railway applications (design code per the evidence) and carries pollution degree 3, overvoltage category III, and energy limitation class 3 — meaning it limits let-through energy enough to protect downstream wiring in a fault.
Thermal derating and ambient limits
The 16 A rating holds at 35 °C ambient. Above that, derate linearly: 15.02 A at 40 °C, 14.51 A at 45 °C, 13.98 A at 50 °C, 13.44 A at 55 °C, and 12.86 A at 60 °C. If the panel internal temperature runs at 50 °C, size the load at 14 A max to avoid nuisance tripping.
Installation and wiring
The IP20 rating applies only with conductors connected; keep the panel door closed during washdown. Sealable, halogen-free, and silicon-free construction suits environments where outgassing or contamination must be avoided — medical, food processing, or clean-room adjacent panels.
