Its 13 A rating at 30 °C (12.26 A at 40 °C, 11.47 A at 50 °C) tells you the continuous current it can carry before thermal trip — important when the panel ambient runs warm.
The 2-module-width body (36 mm) occupies two 18 mm slots in a distribution board. Mounting position is any orientation — no derating needed for horizontal or inverted fit. The sealable feature (padlockable toggle) allows locking in the OFF position for lockout/tagout procedures. Supplementary devices like auxiliary switches or shunt trips can be added via the product extension interface.
Rated and marked per EN 60898 for breaking capacity (6 kA). The halogen-free and silicon-free construction is relevant for environments sensitive to corrosive off-gassing (data centers, clean rooms, medical facilities). The part is classified as energy limitation class 3, meaning it limits let-through energy to a defined level for downstream component protection.
