Breaking capacity is 4.5 kA per EN 60898 and 25 kA per IEC 60947-2. The 4.5 kA EN 60898 rating applies in a domestic or light-commercial distribution board. Either way, the device is energy-limiting class 3, so it restricts let-through energy on a short-circuit, protecting downstream wiring and connected loads. Rated 6 A at 30 °C ambient; derate to 5.7 A at 40 °C, 5.4 A at 50 °C, 5.1 A at 60 °C, and 4.62 A at 70 °C. In a crowded panel with internal temperature above 40 °C, the actual continuous load must stay under the derated value — the thermal-magnetic trip element responds to both current and ambient heat. The device occupies 2 modular width units (36 mm) on a 35 mm DIN rail, with a depth of 77 mm and installation depth of 70 mm. Supply can enter from either top or bottom — no mandatory line/load orientation.","metaTitle":"Siemens 5SU1353-1KK06 SENTRON RCBO, 6 A, C-curve, 1P+N, 4.5","metaDescription":"Siemens 5SU1353-1KK06 SENTRON RCBO, 6 A rated, C tripping characteristic, 1P+N, 4.5 kA per EN 60898, 25 kA per IEC 60947-2.
