Tripping characteristic is B-curve (3–5× In instantaneous trip), so it's sized for resistive and general-purpose loads — lighting, small heaters, control transformers — where inrush isn't high enough to nuisance-trip a C-curve. On a food-and-bev line I'd use this for the panel lighting and convenience outlets, not motor circuits. At 400 V AC that's enough headroom for most industrial panel sub-distribution. If your upstream transformer is large enough to push fault current past 20 kA at the board, you'll need a current-limiting upstream device — but for a typical 630 kVA transformer feeding a MCC, this holds. It also carries a 15 kA DC rating per IEC 60947-2 at 60 V DC (max 72 V DC), which covers DC auxiliary circuits or battery-backed control busses — useful if you're feeding a 48 V DC control loop from the same panel. The 90 mm height fits under any standard 120 mm tall enclosure backplate. Not for wet environments, but fine inside a Type 1 or Type 12 enclosure. Fastening method is quick-assembly system (the standard SENTRON clip), and the unit is sealable for metering or lockout-tagout compliance. ## Environmental range and compliance Ambient temperature range is -40 °C to +75 °C, with humidity derating above 55 °C (95% RH at 55 °C, down to 35% RH at 75 °C). That covers unheated outdoor enclosures in cold climates and hot panel interiors near drives or transformers. Certified to IEC / EN 60898-1 (the MCB standard for household and similar installations) and IEC / EN 60947-2 (the industrial circuit-breaker standard). Also carries UL 1077 and CSA C22.2 No. 235 recognition for supplementary protection in North American panels — 5 kA at AC per those standards. Overvoltage category III (fixed installation, not plug-connected equipment). Energy limitation class 3 — the highest class, meaning it limits let-through energy effectively during a fault, reducing stress on downstream components.","metaTitle":"Siemens 5SY4616-6 SENTRON MCB, B-Curve 4-Pole 10kA","metaDescription":"Siemens 5SY4616-6 SENTRON miniature circuit breaker, 4-pole 3P+N, B-curve, 10kA (IEC 60898) / 20kA (IEC 60947-2).
