That 10 kA figure is the conditional rated short-circuit current (IΔn = 0.5 kA per IEC 61008-1), which means the RCCB is backed by a series fuse rated max 63 A to handle fault currents above its own breaking capacity. The 70 mm depth fits standard 60 mm grid-spaced distribution boards. IP20 with connected conductors, so it needs an enclosure or distribution board cover for finger-safe operation.","metaTitle":"Siemens 5SV4312-0MB SENTRON RCCB, 2-pole, 25 A, 30 mA, Type","metaDescription":"Siemens SENTRON 5SV4312-0MB RCCB, 2-pole Type AC, 25 A, 30 mA, 230 V, 10 kA SCCR.
