It combines earth leakage and short-circuit/overload protection in a single 36 mm wide module, rated for 10 A with a C tripping characteristic and a 4.5 kA breaking capacity per EN 60898. Supply can enter from either top or bottom, so you don't have to rework busbar routing if the panel was originally wired for a different brand. The 2 width units (36 mm) match the standard SENTRON modular footprint. ## Thermal derating — the real-world current rating At 40 °C it derates to 9.5 A, at 50 °C to 9 A, and at 60 °C to 8.5 A. If the panel runs hot — say 65 °C inside a sealed enclosure — the continuous current drops to 8.1 A. That matters when sizing for a continuous load near the nameplate rating. ## Conductor sizing and wiring Halogen-free and silicon-free construction.","metaTitle":"Siemens 5SU1353-1KL10 SENTRON RCBO, 10A C-curve, 4.5kA","metaDescription":"Siemens 5SU1353-1KL10 SENTRON RCBO, 2-pole 1P+N, 10A rated, C tripping characteristic, 4.5kA breaking capacity per EN 60898.
