The short-circuit current rating (SCCR) is 6 kA per IEC 61008-1, and the permissible let-through current is 5,200 A with an I²t value of 58,000 A²·s. The 70 mm depth matches the standard SENTRON RCCB/MCB footprint, so it aligns with busbars and adjacent devices in a Siemens distribution board without extra spacing. Rated IP20 with conductors connected and the distribution board installed — that's touch-safe but not washdown-rated. Keep it inside a closed enclosure; it's not meant for outdoor or wet-area exposure. If your panel runs hotter, you'll need to derate per the thermal curve — but at standard 30 °C ambient it handles the full 40 A without issue. The 30 mA trip threshold is the standard for personnel protection (GFCI class); for equipment protection you'd typically go higher, but this is the right pick for socket-outlet circuits in residential or light commercial. Overvoltage Category III means it's rated for fixed-installation distribution panels (not for sensitive electronics). The silicon-free construction (yes) is a plus for environments where silicone outgassing can contaminate contacts or optics — a detail that matters in automotive paint shops or cleanroom-adjacent panels.","metaTitle":"Siemens 5SV5314-0FB SENTRON RCCB, 2-pole, 40 A, 30 mA, Type","metaDescription":"Siemens SENTRON 5SV5314-0FB RCCB, 2-pole, 40 A, 30 mA, Type AC, 230 V, 50 Hz, 6 kA SCCR, DIN rail mount.
