The 1P+N design switches the live pole and breaks the neutral, but only the live pole is protected against overcurrent. Inside a warm enclosure — say 40 °C — the continuous current drops to 15.04 A; at 45 °C it's 14.56 A; at 50 °C it's 13.92 A; at 55 °C it's 12.96 A. If your panel runs hot (typical for a crowded DIN-rail cabinet), size the upstream protection and the load accordingly. The RCBO is rated for any mounting position, so vertical or horizontal orientation in the enclosure doesn't change the derating curve. The supply can be fed from either top or bottom, which simplifies busbar routing in a crowded distribution board. Rated IP20 (with the distribution board installed and conductors connected), it's intended for indoor, dry-location use inside a closed panel. The operating temperature range (-40 to 75 °C) covers cold storage and hot machine rooms alike. Surge voltage resistance is 4 kV, and surge current withstand (8/20 µs) is 1 kA. Energy limitation class 3 means the let-through energy is low enough to protect downstream equipment under most fault conditions.","metaTitle":"Siemens SENTRON 5SU9654-7KK16 RCBO, 16 A C-curve, 10 kA, 1P+","metaDescription":"Siemens SENTRON 5SU9654-7KK16 RCBO, 16 A rated at 30 °C, C-curve, 10 kA breaking capacity per EN 60898 & IEC 60947-2, 1P+N, 230/240 V AC, halogen-free.
