It carries the SIGRES designation, meaning it is built for harsh ambient conditions — condensation, salt spray, and aggressive industrial atmospheres — without needing an enclosure upgrade. The unit is instantaneous-trip (no short-time delay), so it clears fast but does not coordinate with delayed RCCBs downstream. Depth is 70 mm, installation depth the same — no extra clearance needed behind the rail. The grid spacing is 60 mm, so it aligns with standard cut-out patterns in SENTRON distribution boards. ## Fault ratings and coordination Rated short-circuit current is 10 kA per IEC 61008-1, with a conditional short-circuit current of 0.8 kA when backed by a series fuse limited to 100 A max. That 0.8 kA figure is the withstand rating under the standard's test sequence — it is not a breaking capacity for the RCCB alone. For fault coordination upstream, the 10 kA SCCR is the number to match against the prospective fault level at the installation point. Power loss per pole at rated current is 1.9 W in hot operating state, which adds up to 7.6 W total for the 4-pole unit — relevant for thermal budgeting inside a sealed enclosure.","metaTitle":"Siemens 5SV3344-6KK12 SENTRON RCCB, 4P, 40 A, 30 mA, 400 V A","metaDescription":"Active-production Siemens 5SV3344-6KK12 SENTRON RCCB, 4-pole, type A, 40 A, 30 mA, 400 V AC, SIGRES rated for harsh ambient conditions.
