It is designed for final circuits in distribution boards where both earth-leakage and short-circuit/overload protection are required in one unit, saving a DIN-rail position compared to separate RCCB and MCB. The design is marked \"Short-time delayed G, super resistant K\" — the residual-current element is a G-type (short-time delayed, typically 10 ms minimum non-tripping time) to avoid nuisance tripping from transient leakage pulses common on electronic loads, and the K suffix indicates enhanced immunity to surge currents (lightning or switching surges) without false operation. The 10 A rating is only valid at 30 °C ambient inside the distribution board. Per the datasheet derating table, at 40 °C the continuous current drops to 9.5 A, at 50 °C to 9 A, at 60 °C to 8.5 A, and at 70 °C to 7.7 A. If your panel runs warm — common in crowded enclosures or near transformers — size the upstream protection and the connected load against the derated figure, not the 30 °C nameplate. ## Environmental and compliance profile","metaTitle":"Siemens 5SU1354-7LB10 SENTRON RCBO, 10A C-curve 1P+N, 10kA E","metaDescription":"Siemens 5SU1354-7LB10 SENTRON RCBO, 10A rated, C characteristic, 1P+N, 10kA per EN 60898 / 20kA per IEC 60947-2.
