Standard Type A RCCBs can miss the high-frequency leakage a VFD injects back onto the line; Type F catches it. The 30 mA trip threshold is the standard for personal protection against indirect contact in TN and TT systems. Four modular-width units (72 mm wide,) snap onto a 60 mm-grid DIN rail. Supply can land top or bottom. Depth is 70 mm — check the enclosure depth before committing; some shallow consumer units need the 70 mm clearance. IP20 only when the distribution board is installed and conductors are connected. ## Fault handling and selectivity The short-time delayed design means it withstands surge currents up to 3 kA without nuisance tripping, and the I²t let-through is rated at 110 000 A²·s. Let-through current is 7 100 A. For coordination, pair it with a 10 kA MCB or fuse; the delay helps the downstream breaker clear a bolted fault first.","metaTitle":"Siemens 5SV3346-3 SENTRON RCCB, Type F, 63 A, 30 mA, 4P","metaDescription":"Siemens 5SV3346-3 SENTRON Type F RCCB, 4-pole, 63 A rated, 30 mA trip, 10 kA SCCR.
