It occupies one modular width (18 mm) and snaps onto standard DIN rail. Breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC. The 440 V insulation voltage (Ui) gives headroom for 400 V line-to-line systems.
Ambient range is -40 to 75 °C with up to 95 % humidity. IP20 with conductors connected; IP40 in the handle area — fine for enclosed panels, but don't leave the front exposed to washdown.
1-pole, C characteristic, 10 kA breaking capacity per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC. Insulation voltage 440 V. Width 18 mm, depth 70 mm, height 110 mm. Ambient temperature range -40 to 75 °C.
Both are 1-pole MCBs on 18 mm width, but the 5SL4363-7 is a 63 A B-curve device with different breaking capacities. The 5SJ4101-7HG41 has a C curve and its ratings differ; verify the load and fault current requirements before swapping. Footprint is the same modular width.
