Mounting position any, so vertical or horizontal rail orientation works.
Rated 40 A at 30 °C; derates to 37.89 A at 40 °C and 34.47 A at 55 °C. Ambient range -40 to 75 °C covers unheated utility rooms and outdoor-rated enclosures. Sealable, so the toggle can be locked in the off position for lockout/tagout.
10 kA per both EN 60898 and IEC 60947-2, so it safely interrupts fault currents up to that level.
Both are 4-pole SENTRON MCBs on the same DIN-rail footprint (72 mm wide, 4 MW). The 5SL4440-6 is rated 40 A B curve; the 5SL4363-7 is a different rating/characteristic. Physical fit is identical — no rewiring needed for the mounting, but verify the load current and trip curve match the circuit design.
The MCB carries approvals per EN 60898 and IEC 60947-2. Halogen-free and silicon-free construction are documented. For RoHS, REACH, and UL declarations, the manufacturer's documentation portal provides the current compliance statements.
