It protects a 1P+N circuit — meaning it switches the live pole and monitors the neutral — which is the standard arrangement for single-phase final subcircuits in European distribution boards. At 30 °C ambient the RCBO carries its full 6 A; at 40 °C it derates to 5.7 A, and at 50 °C to 5.4 A, all the way down to 4.62 A at 70 °C. That derating curve is important if you're packing this into a crowded enclosure where internal temperature runs high — the 6 A label is only good at the reference temperature. Mount it in any position, which helps when retrofitting into an existing board with limited rail orientation. The IP20 rating applies once the distribution board is installed with conductors connected; the front face is touch-safe but the terminals need enclosure protection.","metaTitle":"Siemens 5SU1656-7KK06 SENTRON RCBO, 6A C-curve, 2-pole","metaDescription":"Siemens 5SU1656-7KK06 SENTRON RCBO, 6A rated, C tripping characteristic, Type A residual current, 2-pole 1P+N, 6kA (EN 60898) / 25kA (IEC 60947-2).
