Rated breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2. That dual rating means it's listed for both residential / light commercial (EN 60898) and industrial panel (IEC 60947-2) duty — the higher 15 kA figure is what matters when the available fault current at the panel is known to exceed 10 kA. Insulation voltage (Ui) is 440 V AC, so it's comfortably within the 400 V line-to-line environment.","metaTitle":"Siemens 5SJ4250-7HG41 SENTRON MCB, 2P C-curve, 10kA","metaDescription":"Siemens 5SJ4250-7HG41 SENTRON 2-pole MCB, C-curve, 10 kA per EN 60898, 15 kA per IEC 60947-2. 400 V AC / 60 V DC.
