The 10 kA short-circuit current rating (SCCR) per IEC 61008-1 and EN 60898 (0.8 kA) defines the fault level it can safely interrupt without upstream protection needing to clear first. Mounts on standard DIN rail (REG) in any position — no orientation restriction. Listed as current production (active lifecycle stage).","metaTitle":"Siemens SENTRON 5SM3624-4 RCCB, Type B, 40 A, 300 mA, 2-Pole","metaDescription":"Siemens SENTRON 5SM3624-4 RCCB, 2-pole type B short-time delayed, 40 A rated, 300 mA trip. 10 kA SCCR.
