Breaking capacity is rated at 10 kA per EN 60898 and 20 kA per IEC 60947-2, which gives the 5SU1354-1LB10 headroom for installation at the origin of a sub-distribution board where fault currents can exceed the lower standard. The design is listed as short-time delayed G and super resistant K, which means the residual-current element tolerates brief surge currents (from lightning or capacitor switching) without nuisance tripping, and the overcurrent element handles higher inrush without degrading — provided the prospective short-circuit current stays within the 20 kA IEC rating. At 40 °C it derates to 9.5 A, at 50 °C to 9 A, and at 60 °C to 8.5 A. By 70 °C the continuous current is 7.7 A. This matters in a sealed enclosure or a crowded DIN rail where internal temperature rise is unavoidable — the designer must either load the circuit below the derated figure or ventilate the panel to keep ambient under 40 °C. Mounting position is unrestricted, which simplifies layout in a vertical or horizontal busbar system. The 5SU1354-1LB10 occupies 2 modular width units (36 mm) on the DIN rail, with an installation depth of 70 mm and overall depth of 77 mm.","metaTitle":"Siemens 5SU1354-1LB10 SENTRON RCBO, 10 A C-curve, 2-pole 1P+","metaDescription":"Siemens SENTRON 5SU1354-1LB10 RCBO, 10 A rated, C tripping characteristic, AC residual current type, 10 kA (EN 60898) / 20 kA (IEC 60947-2) breaking capacity.

The 5SY7210-7CC is a different class (MCB only, no residual-current element), so the functional replacement requires verifying the circuit's RCD protection requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU1354-1LB10","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/5SU1354-1LB10 when reusing this data.
