The 30 mA residual sensitivity covers personnel protection (indirect contact) and fire prevention in standard AC circuits. Breaking capacity is 4.5 kA per EN 60898 for domestic/commercial panels, and 15 kA per IEC 60947-2 for industrial distribution boards — the higher figure gives selectivity headroom in sub-distribution. ## Installation and wiring notes Terminals accept solid or stranded conductors from 1.5 to 25 mm², with a tightening torque of 2.5 to 3 N·m. Supply can enter from top or bottom — no polarity restriction on the line side. Neutral conductor switching is built in, so no separate neutral bar is needed downstream. Rated IP20 once installed in a distribution board with connected conductors — the enclosure provides the environmental seal.","metaTitle":"Siemens 5SU1323-1WM25 SENTRON RCBO, 25A C-Curve 30mA 2P 4.5k","metaDescription":"Siemens SENTRON 5SU1323-1WM25 RCBO, 25A rated, C tripping characteristic, 30mA residual current, 2-pole, 4.5kA (EN 60898) / 15kA (IEC 60947-2).
