Rated 16 A at 230 V AC with a C-curve tripping characteristic, it is sized for residential and light-commercial branch circuits where moderate inrush (motor starts, capacitor banks) is expected. The 6 kA breaking capacity per EN 60898 covers most domestic and small-panel fault levels. It snaps onto standard DIN rail, takes 2 modular width units (36 mm), and the 76 mm depth leaves room for wiring in a shallow enclosure. ## What the ratings mean for your panel The C-curve (tripping between 5 and 10 times rated current) means this breaker holds through the short-duration inrush of a motor or a bank of LED drivers without nuisance tripping, but still clears a hard fault fast. At 30 °C it carries the full 16 A; at 40 °C the rated current derates to 14.78 A, at 45 °C to 14.08 A, and at 55 °C to 12.74 A — so if the panel runs hot, down-rate the connected load accordingly. The 6 kA breaking capacity (per both EN 60898 and IEC 60947-2) is the maximum fault current it can safely interrupt; if your service entrance has a higher prospective short-circuit current, you need an upstream current-limiting device. The IP20 rating (with connected conductors) is standard for a DIN-rail enclosure — no washdown rating, so keep it inside a dry panel.","metaTitle":"Siemens 5SL6516-7BB SENTRON MCB, 1P+N, C-curve, 16 A, 6 kA","metaDescription":"Siemens 5SL6516-7BB SENTRON miniature circuit breaker, 1P+N, C-curve, 16 A, 6 kA per EN 60898, 230 V AC.

The 5SL6516-7BB is the Italy-specific version; the 5SL6016-7KL may be the pan-European equivalent. Both occupy the same 2 MW footprint and mount on the same DIN rail, so a swap is mechanically straightforward, but check the breaking capacity rating for your fault level."},{"question":"Who supplies 5SL6516-7BB and how is it quoted for volume purchases?","answer":"We source and quote this part to order against an RFQ through independent distribution.
