This breaker carries two breaking-capacity ratings because it's certified under both product and industrial standards. Per EN 60898 (the household / commercial standard) it's rated 10 kA at 230 V AC. Per IEC 60947-2 (the industrial standard for panel builders) it's rated 20 kA at 230 V AC, and 15 kA at 60 V DC. For UL 1077 / CSA C22.2 No. 235 applications it's rated 5 kA.
IP20 with conductors connected.
76 mm overall; installation depth is 70 mm.
Both are 2-module-width (36 mm) SENTRON MCBs with the same DIN-rail footprint and terminal layout, so a direct mechanical swap is possible. Verify the tripping characteristic and breaking capacity match your coordination study — the 5SY4101-7CV is a different current rating and may have a different curve.
