Mounting position any, which helps when the panel layout gets tight. IP20 with conductors connected — fine inside a cabinet, not for wet areas.
Rated to IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 / CSA C22.2 No.235. Halogen-free and silicon-free, which matters if the panel lives near sensitive electronics or in a low-smoke zone. Temperature range -40 °C to 75 °C, with derating above 55 °C (95% RH to 55 °C, then dropping to 35% at 75 °C).
Both are 2-pole MCBs with C-curve, but the 5SL4363-7 is a different series with different breaking capacities and possibly different dimensions. The 5SY6240-7 is 36 mm wide (2 MW), so it fits the same DIN-rail footprint, but verify the terminal layout and busbar compatibility against your panel drawing before committing the BOM line.
The 5SY6240-7 is certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 / CSA C22.2 No.235. It is halogen-free and silicon-free. Compliance declarations (CE, UKCA, etc.) are available with the shipment.
