It's rated 20 A with a C tripping characteristic — the standard choice for general-purpose loads like lighting circuits, small motor starters, and socket outlets in residential and light commercial infrastructure. The 6 kA breaking capacity per EN 60898 is enough for most domestic and small commercial distribution boards where the prospective fault current stays under that threshold. It operates on a single-phase 230 V AC supply at 50/60 Hz. ## Panel fit and integration Occupies 2 modular width units (36 mm) on a DIN rail, with a depth of 76 mm and a standard 70 mm installation depth behind the panel. Mounting position is any, so it fits in vertical or horizontal distribution boards. IP20 with connected conductors — fine inside a closed panel, not for wet locations. Sealable design allows padlocking in the OFF position for lockout/tagout. Accepts supplementary devices (auxiliary contacts, shunt trips, alarm switches) for remote status or emergency shutdown integration.","metaTitle":"Siemens 5SL6520-7CC SENTRON MCB, 1P+N, C-Curve, 20 A, 6 kA","metaDescription":"Siemens 5SL6520-7CC SENTRON miniature circuit breaker, 1P+N, 20 A, C-curve, 6 kA breaking capacity per EN 60898, 230 V AC.

The difference is pole design: 5SL6520-7CC is 1P+N (switched neutral, protected phase), while 5SL6220-7 is 2P (both poles protected). If the panel was wired for a 2P breaker with both poles protected, dropping in a 1P+N unit means the neutral is switched but not overcurrent-protected — verify the circuit design before swapping."},{"question":"What compliance documentation is available for 5SL6520-7CC?","answer":"The 5SL6520-7CC is halogen-free and silicon-free, rated for overvoltage category III and pollution degree 2.

For specific RoHS, REACH, or UL documentation, request the manufacturer's declaration at quote time — these are standard for the SENTRON line."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL6520-7CC","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SL6520-7CC when reusing this data.
