At 4.5 kA it also covers the residential final-circuit requirement. Supply cord can enter from top or bottom — no forced busbar orientation on this design. Mounting position is any, so vertical or horizontal panel layouts work equally. ## Temperature derating — real-world current capacity At 40 °C it derates to 15.2 A; at 50 °C to 14.4 A; at 60 °C to 13.6 A; and at 70 °C to 12.32 A. ## DIN-rail footprint and mounting Two modular-width units (36 mm wide) on standard DIN rail. Depth is 77 mm, installation depth 70 mm. Height 90 mm. The 1P+N construction means the neutral pole is switched internally — no separate neutral bar needed downstream, which saves a terminal position in the distribution board. IP20 rating applies when installed in a distribution board with connected conductors. That's normal for enclosed panels; no special washdown or outdoor sealing on this unit.","metaTitle":"Siemens 5SU1353-1KK16 SENTRON RCBO, 16 A C-curve, 1P+N","metaDescription":"Siemens SENTRON RCBO 5SU1353-1KK16, 16 A rated at 30 °C, C tripping characteristic, 1P+N, 4.5 kA (EN 60898) / 15 kA (IEC 60947-2).
