Per EN 60898 (domestic / light commercial) it is rated 6 kA — fine for a sub-distribution board or final circuit. Per IEC 60947-2 (industrial) it carries 15 kA, which gives headroom for a main distribution panel with a larger upstream transformer. The energy limitation class is 3, so it lets through less let-through energy than a class-1 or class-2 device, making downstream coordination easier. ## Thermal derating — the real-world current The 13 A rating holds only at 30 °C. At 40 °C it derates to 12.48 A; at 50 °C to 11.96 A; at 60 °C to 11.31 A; at 70 °C to 10.01 A. If the panel ambient runs warm — say 50 °C inside a sealed enclosure — the usable current is 11.96 A, not 13 A.","metaTitle":"Siemens SENTRON 5SU1656-7KK13 RCBO, 2-pole 13 A C-curve, 6/1","metaDescription":"Siemens SENTRON 5SU1656-7KK13 RCBO, 2-pole 1P+N, 13 A, C-curve, Type A residual current, 6 kA (EN 60898) / 15 kA (IEC 60947-2).

The 5SU1656-7KK13 is an RCBO combining overcurrent and Type A RCD in one 2-MW package. They share the same 36 mm width and DIN-rail footprint, so the RCBO can drop into a panel originally wired for the MCB without rewiring the busbar, but the neutral connection must be routed through the RCBO for the residual-current function to work."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU1656-7KK13","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/5SU1656-7KK13 when reusing this data.
