But as the panel warms up — and it will, with other breakers and contactors sharing the enclosure — the rated current drops steadily: 9.5 A at 40 °C, 9 A at 50 °C, 8.5 A at 60 °C, and 8 A at 70 °C. If you're populating a densely packed consumer unit or a small distribution board, you need to check the actual ambient temperature at the breaker's location, not the room temperature. A 10 A circuit loaded to 9 A continuous in a 50 °C panel is already at its limit — no headroom for a startup surge. The installation depth is 70 mm (body depth 77 mm including the front projection), so it fits standard 80 mm deep distribution boards. IP20 is the rating, but that's only valid when the distribution board is installed and the conductors are connected — the front face is touch-protected (finger-safe), but the terminals aren't sealed against dust ingress until the board cover is on.","metaTitle":"SENTRON 5SU1656-6KK10 RCBO, 2-pole, 10 A, Type A, 6 kA","metaDescription":"SENTRON 5SU1656-6KK10 RCBO, 2-pole, 10 A, B-curve, Type A, 6 kA (EN 60898) / 15 kA (IEC 60947-2).

The 5SU1656-6KK10 is an RCBO, so it's deeper (77 mm vs the MCB's typical 70 mm) and requires a neutral connection for the residual current electronics. The 36 mm width (2 MW) is the same, but the wiring and the space behind the DIN rail need to accommodate the extra depth and the neutral tail."},{"question":"What compliance documentation is available for this part?","answer":"The device is halogen-free and silicon-free, rated for overvoltage category III and pollution degree 2. It carries EN 60898 and IEC 60947-2 ratings. The manufacturer provides the usual CE declaration, RoHS and REACH compliance statements with the product documentation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU1656-6KK10","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/5SU1656-6KK10 when reusing this data.
