Breaking capacity is rated at 4.5 kA per EN 60898 (the domestic-standard test) and 15 kA per IEC 60947-2 (the industrial-standard test). Rated IP20 with the distribution board installed and conductors connected — this is a panel-interior device, not for wet-area standalone use. The supply can enter from either top or bottom, and the neutral conductor is switched internally.","metaTitle":"Siemens 5SU1323-1WM20 SENTRON RCBO, 2P C20A 30mA AC, 4.5kA","metaDescription":"Siemens SENTRON 5SU1323-1WM20 RCBO, 2-pole, C20A, 30mA AC type, 4.5kA (EN 60898) / 15kA (IEC 60947-2).
