The Siemens 5SU1353-1KL13 is a SENTRON-series RCBO combining overcurrent and residual current protection in a single 2-module (36 mm wide) package. It protects a single-phase circuit (1P+N, one protected pole) at 13 A rated current with a Type C tripping characteristic — meaning it holds through mild inrush (5–10× rated) and trips fast on short-circuit. Breaking capacity is 4.5 kA per EN 60898, 5 kA per IEC 60947-2, which covers most residential and light commercial distribution boards.
In a crowded enclosure at 40 °C it carries 12.48 A; at 50 °C it's 11.96 A; at 60 °C it's 11.31 A; at 70 °C it's 10.01 A. If your load is continuous near 13 A and the panel runs hot, step up one frame size or derate per this curve.
Width of 36 mm (2 modular units), depth of 77 mm, installation depth of 70 mm — fits standard DIN-rail enclosures. Mounting position is unrestricted. IP20 with conductors connected and distribution board installed — not for wet environments.
Halogen-free and silicon-free construction. Rated insulation voltage 264 V, surge voltage resistance 4 000 V. Energy limitation class 3. Compliance documentation (RoHS, REACH, CE) is standard for the SENTRON series; contact our team for specific declarations if needed for your quality file.
