The 2 MW width (36 mm) leaves room for adjacent breakers in a crowded DIN rail; mounting position is unrestricted, and the supply can enter from top or bottom, which simplifies busbar layout.","metaTitle":"Siemens 5SU1654-1KK20 SENTRON RCBO, 20 A, C-curve, 10 kA","metaDescription":"Siemens SENTRON 5SU1654-1KK20 RCBO, 1P+N, 20 A rated, C tripping characteristic, 10 kA (EN 60898) / 20 kA (IEC 60947-2) breaking capacity.
