Residual-current element is Type AC, rated at 300 mA. Type AC detects sinusoidal AC earth faults only. ## Breaking capacity and fault clearing Energy limitation class 3 means it restricts let-through energy enough to protect downstream wiring and loads from thermal damage during a short circuit. Width is 36 mm (2 modular units), depth 70 mm — the same footprint as a 2-pole SENTRON MCB, so it fits existing distribution boards without extra spacing. Rated for overvoltage category III (distribution-level surge withstand) and pollution degree 2 (non-conductive dust, occasional condensation).","metaTitle":"Siemens 5SU1654-1RC10 SENTRON RCBO, 10 A, C-curve, 300 mA Ty","metaDescription":"Siemens SENTRON 5SU1654-1RC10 RCBO, 2-pole, 10 A, C characteristic, 300 mA residual current Type AC. 10 kA per EN 60898, 20 kA per IEC 60947-2.

However, the 5SL6550-7BB is a plain MCB with no residual-current protection — the RCBO adds earth-leakage detection and requires the neutral conductor to pass through its internal neutral pole.
