Rated 16 A at 30 °C, the part carries a full thermal derating table through 70 °C — at 40 °C it's 15.2 A, at 50 °C 14.4 A, at 60 °C 13.6 A, and at 70 °C 12.8 A (–). That matters for a crowded enclosure: if the panel ambient runs 50 °C, the continuous load limit drops to 14.4 A, not the nameplate 16 A. Breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 — sufficient for most commercial and light industrial sub-distribution where the upstream transformer limits fault current below those levels. The housing is 1 MW wide (18 mm per), depth 77 mm, installation depth 70 mm. Mounting position any, supply feed either top or bottom. IP20 with the distribution board installed and conductors connected — it's a panel-interior device, not a field-mounted enclosure.
Degree of pollution 2, overvoltage category III. Energy limitation class 3. Surge voltage resistance 4 000 V. Insulation voltage (Ui) rated 253 V.
