At 18 mm wide it occupies one modular unit on a DIN rail, leaving room for other breakers in a multi-pole assembly.
The quick-assembly fastening method lets you gang multiple units without tools. Installation depth is 70 mm from the DIN rail face; overall depth 76 mm. Verify your enclosure's gland plate clearance — 6 mm extra beyond the rail depth matters in shallow boxes.
6 kA at 400 V AC per EN 60898, and 5 kA at the same voltage per UL 1077 and CSA C22.2 No.235.
The MCB carries approvals per EN 60898, UL 1077, and CSA C22.2 No.235. It is halogen-free and silicon-free. Standard Siemens documentation includes CE declaration, RoHS, and REACH compliance sheets.

Both are 1-pole SENTRON MCBs with the same 18 mm width and DIN-rail mounting. The 5SY6103-7CC uses a C-curve while the 5SY4101-7CV uses a different characteristic — check coordination in your selectivity study before swapping, but the physical footprint is identical.
