It occupies a single modular width (18 mm) on a DIN rail, protecting a single phase (1P+N, 2 poles total) with a C-curve magnetic trip characteristic rated at 10 A at 30 °C ambient.
The 10 A rating holds up to 30 °C. Above that, the thermal element derates: 9.4 A at 40 °C, 9.1 A at 45 °C, 8.8 A at 50 °C, 8.4 A at 55 °C, 8.1 A at 60 °C, 7.7 A at 65 °C, and 7.4 A at 70 °C. If the panel is sealed or sitting next to a heat source, size the load to the derated figure for the actual cabinet ambient — the 7.4 A at 70 °C is the floor, not a margin. Mounting position is unrestricted, and supply can enter from top or bottom — no orientation constraints during panel layout.
Breaking capacity and fault coordination
Dimensions: 18 mm wide (1 MW), 90 mm high, 77 mm deep, with 70 mm installation depth behind the panel face. The IP20 rating applies only when installed in a distribution board with conductors connected — it is not a standalone enclosure rating.
