Under a fault, the 30 mA device trips first, keeping the 5SV3444-8 closed and maintaining supply to the rest of the board. The short-circuit current rating (SCCR) is 10 kA per IEC 61008-1, with a let-through current of 5,200 A and an I²t value of 58,000 A²·s — figures that inform upstream fuse or MCB selection for full discrimination. ## Temperature derating and installation Mounting position is any orientation. Silicon-free construction suits potting or coating processes in sensitive environments.","metaTitle":"Siemens SENTRON 5SV3444-8 RCCB, 40 A, 100 mA, Type A, Select","metaDescription":"Siemens SENTRON 5SV3444-8 selective RCCB, 4-pole, 40 A rated current, 100 mA residual current, Type A, 10 kA SCCR.
