It protects final circuits against overload, short-circuit, and earth leakage in one DIN-rail unit, saving panel space over separate devices. Rated 230/240 V AC at 50 Hz, it carries a 10 kA breaking capacity per EN 60898 and 20 kA per IEC 60947-2 — the higher IEC figure matters for industrial panels where fault currents can exceed domestic levels. Mounts in any position; feed from top or bottom. Neutral conductor is switched internally (1P+N), so the neutral pole opens with the line — no separate neutral bar needed downstream. Touch-protected terminals reduce arc-flash risk during maintenance.","metaTitle":"Siemens 5SU1654-7KK25 SENTRON RCBO, 25 A C-curve 300 mA Type","metaDescription":"Siemens SENTRON 5SU1654-7KK25 RCBO, 25 A, C-curve, 300 mA Type A, 10 kA (EN 60898) / 20 kA (IEC 60947-2), 2-pole 1P+N, 2 MW, halogen-free.
