The Siemens SENTRON 5SV3311-6 is a 2-pole residual current circuit breaker (RCCB), type A, rated 16 A with 30 mA sensitivity, for 230 V AC 50 Hz systems. It's a fast-mover for panel builders and MRO planners — the kind of part you keep on the shelf for line-down protection swaps. Rated short-circuit withstand is 10 kA per IEC 61008-1, with a 0.5 kA conditional rating under that standard. The 30 mA trip threshold covers basic shock protection and fire risk in residential and commercial distribution boards.
Depth is 70 mm, height 90 mm — matches the SENTRON family footprint. Mounts in any position; supply can enter top or bottom. IP20 with the distribution board installed and conductors connected. Installation depth matches the overall depth at 70 mm, so no extra clearance behind the rail. Grid spacing is 60 mm — standard for modular enclosures.
