It is designed for 400 V AC multi-phase operation, handles 50/60 Hz, and occupies 3 modular width units (54 mm) on a DIN rail. The 1.8 W power loss per pole at rated current in hot operating state is modest — 5.4 W total for the 3-pole unit — so derating within a multi-device enclosure is manageable. The mechanical service life of 10 000 operating cycles is typical for this class; the part is not intended for frequent switching duty (use a contactor for that). The part carries the Italy-specific version suffix (6BB), which typically affects packaging language and regional catalog listing — the functional ratings are identical to the standard 5SL6316-6 variant. For BOM traceability, the nameplate matches the order code exactly; no substitution without requalification. ## Panel integration Depth is 76 mm (installation depth 70 mm behind the panel surface), width 54 mm (3 MW units), height 90 mm. The 3-pole footprint matches the standard SENTRON 5SL family — same housing dimensions as the 5SL4363-7 (C-curve, 10 kA) and the 5SL6120-7 (1-pole, C-curve).","metaTitle":"Siemens 5SL6316-6BB SENTRON MCB, 3P B-Char 16A 6kA","metaDescription":"Siemens 5SL6316-6BB SENTRON miniature circuit breaker, 3-pole, B-curve, 16 A, 6 kA per EN 60898.

The difference is the tripping curve (B vs C) and the breaking capacity (6 kA vs 10 kA). The 5SL4363-7 is a C-curve 63 A unit with 10 kA; the 5SL6316-6BB is a B-curve 16 A unit with 6 kA. If the panel was designed for a 3-pole SENTRON MCB, the 5SL6316-6BB fits mechanically, but the electrical ratings must match the circuit design."},{"question":"Where can I buy the 5SL6316-6BB?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
