It protects branch circuits in residential and light commercial panels where the load is mostly resistive or has a modest inrush, like lighting, general-purpose outlets, or small appliances. The B-curve trips between 3 and 5 times rated current, so it clears a short fast enough to keep the downstream wiring from cooking, but it won't nuisance-trip on the mild startup surge of a refrigerator or a row of fluorescents. The 6 kA breaking capacity is the same under both EN 60898 (household standard) and IEC 60947-2 (industrial standard), so this breaker is accepted in both residential panels and industrial sub-distribution boards where the prospective fault current stays under that figure. The 1P+N pole design switches the line and switches the neutral, which is required in many regional codes for final subcircuits — the neutral is not just a solid bar pass-through. It occupies 2 modular width units (36 mm) on a DIN rail, installs in any mounting position, and accepts supplementary devices (auxiliary switches, shunt trips, alarm contacts) for remote status or emergency-off integration. The IP20 rating with connected conductors means it's intended inside a distribution board or enclosure — not exposed to washdown or outdoor weather. ## Panel fit and physical integration The 36 mm width (2 MW) and 76 mm depth are standard for SENTRON 5SL6-series breakers. It drops into the same DIN-rail footprint as the 5SL6516-6YA variant (same dimensions, same ratings) — no rewiring or busbar repositioning required if you're swapping between those two. The 70 mm installation depth leaves room for wiring behind the breaker in a standard distribution board.","metaTitle":"Siemens 5SL6516-6 SENTRON MCB, 16A B-Curve 1P+N, 6kA","metaDescription":"Siemens 5SL6516-6 SENTRON miniature circuit breaker, 16 A, B-curve, 1P+N, 6 kA breaking capacity per EN 60898/IEC 60947-2, 230 V AC.
