The DC rating covers battery-backed control circuits common in mining substations. ## Thermal derating — don't ignore the fine print At 35 °C it carries the full 16 A. At 40 °C that drops to 15.23 A, at 50 °C to 14.43 A, and at 60 °C to 13.57 A. If you're packing this breaker into a dense DIN-rail enclosure next to contactors and drives running at 50 °C internal ambient, you need to size the load at 14.43 A, not 16 A.","metaTitle":"Siemens SENTRON 5SY4516-5 Miniature Circuit Breaker, 16 A, T","metaDescription":"Siemens SENTRON 5SY4516-5 miniature circuit breaker, 16 A rated current, 10 kA breaking capacity per EN 60898, 2-pole 1P+N design.

The 20 kA rating covers industrial fault levels; the DC rating handles battery-backed control circuits."},{"question":"What does the Type A characteristic mean on this breaker?","answer":"Type A trips on both overload and short-circuit but also detects low-level arcing faults (typically 3–5 times rated current) that a Type B or C curve might pass. This makes it suitable for protecting semiconductor loads or long cable runs where arc-fault detection is needed."},{"question":"Where can I buy 5SY4516-5 and get current pricing?","answer":"The 5SY4516-5 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time."},{"question":"Will 5SY4516-5 drop into a panel specified around 5SY7210-7CC?","answer":"Both are 2-module-width (36 mm) SENTRON MCBs with the same DIN-rail footprint and terminal layout, so the 5SY4516-5 fits the same panel cutout and busbar arrangement. The difference is the tripping characteristic: Type A on the 5SY4516-5 versus Type C on the 5SY7210-7CC, and the rated current — 16 A versus the peer's rating. Verify the load current and required curve before swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY4516-5","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SY4516-5 when reusing this data.
