This RCBO carries two breaking-capacity ratings: 4.5 kA per EN 60898 (the domestic-and-similar-installation standard) and 15 kA per IEC 60947-2 (the industrial standard). The higher IEC figure means it can be applied in commercial or light-industrial distribution boards where fault currents exceed 6 kA, as long as the upstream device coordinates. The 1 kA surge-current withstand (8/20 µs waveform) tells you it won't nuisance-trip on lightning-induced surges common in outdoor-fed panels. ## Installation and wiring notes Snaps onto DIN rail — any mounting position, 70 mm installation depth. Screw terminals accept 0.75 to 35 mm² solid or stranded copper, torqued to 2.5–3 N·m. Halogen-free and silicon-free construction suits clean-room or high-reliability builds where outgassing matters.","metaTitle":"Siemens 5SU1353-1WM08 SENTRON RCBO, 8A C-curve 30mA 1P+N","metaDescription":"Siemens 5SU1353-1WM08 SENTRON RCBO, 8A rated, C-curve, 30mA residual current, 1P+N, 4.5kA (EN 60898) / 15kA (IEC 60947-2).
