Rated 16 A at AC, but that figure holds only up to 45 °C ambient. At 50 °C it derates to 15.5 A, and at 55 °C to 14.99 A (–). The 30 kA breaking capacity at 400 V AC (IEC 60947-2) is the figure that governs fault clearance in industrial distribution; the 5 kA rating under UL 1077 and CSA C22.2 No. 235 is the supplementary-protector limit for North American panels. For DC circuits, it breaks 15 kA per the same IEC standard. The housing is IP20 with conductors connected, so it needs an enclosure for washdown or outdoor use; it is not a standalone weatherproof device. The breaker carries IEC 60947-2, UL 1077, and CSA C22.2 No. 235 approvals. Vibration resistance per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz. The product is sealable — a lockable cover can be fitted to prevent unauthorized reset.","metaTitle":"Siemens 5SY8116-8 SENTRON MCB, D Curve, 16 A, 1-Pole","metaDescription":"Siemens 5SY8116-8 SENTRON miniature circuit breaker, 1-pole, D tripping characteristic, 16 A rated at AC, 30 kA breaking capacity per IEC 60947-2.

Verify the rated current and breaking capacity against your load before substituting, as the 5SY7210-7CC carries different amperage and interrupting ratings."},{"question":"Will 5SY8116-8 drop into a panel specified for 5SY7210-7CC?","answer":"Both are 1-module-width SENTRON breakers on DIN rail, so the mechanical footprint is the same. No rewiring of the busbar or enclosure cutout is needed. Confirm the current rating and breaking capacity match your circuit protection requirements."},{"question":"What compliance documentation does Siemens provide for 5SY8116-8?","answer":"The breaker is certified to IEC 60947-2, UL 1077, and CSA C22.2 No. 235. It is halogen-free and silicon-free. Standard Siemens declarations of conformity (CE, UKCA) and material compliance (RoHS, REACH) are available on request."},{"question":"Where can I buy 5SY8116-8 and how is it quoted?","answer":"Sourced to order through independent distribution.
