The short-time delayed design (selective/S) avoids nuisance tripping when downstream equipment generates brief inrush or leakage pulses, so it coordinates with sub-feed RCCBs on the same distribution board. Rated short-circuit current withstand is 10 kA per IEC 61008-1, with a permissible let-through current of 7 000 A and an I²t value of 60 000 A²·s. Surge current resistance is rated at 3 kA (8/20 µs waveform). Depth is 70 mm including the terminals. ## Temperature derating — the real-world ampacity Above that, derate linearly: 72 A at 55 °C, 64 A at 60 °C, 56 A at 65 °C, and 48 A at 70 °C.","metaTitle":"Siemens 5SV3347-4 SENTRON RCCB, Type B, 80 A, 30 mA, 4P","metaDescription":"Siemens 5SV3347-4 SENTRON RCCB, Type B, 80 A rated, 30 mA trip, 4-pole, short-time delayed. 10 kA SCCR, DIN rail mount.
