Breaking capacity is 6 kA per EN 60898 and 15 kA per IEC 60947-2, with a 5 kA rating under UL 1077 / CSA C22.2 No. 235 for North American panels. Neutral pole switches with the phase poles, which simplifies wiring in a 3P+N distribution board. ## Panel fit and environmental tolerance Mounts via the quick-assembly system (DIN rail) in any position. Ambient range from -40 °C to 75 °C, with humidity derating above 55 °C (max 95% RH to 55 °C, then 55% to 70 °C, then 35% to 75 °C). Halogen-free and silicon-free construction; sealable to prevent tampering. Overvoltage category III, so it's rated for fixed-installation mains supply. Rated and marked per EN 60898 (6 kA) and IEC 60947-2 (15 kA at 400 V AC, 15 kA at 72 V DC). Also carries a UL 1077 / CSA C22.2 No. 235 rating at 5 kA for supplementary protection use in North American panels. The product designation follows DIN EN 61346-2 and DIN EN 81346-2 (function code F). Touch protection is integrated. For RoHS, REACH, and full declaration of conformity, the manufacturer provides these on request with the order documentation.","metaTitle":"Siemens 5SY6616-8 SENTRON MCB, 4P D-16 A, 400 V AC","metaDescription":"Siemens 5SY6616-8 SENTRON miniature circuit breaker, 4-pole 3P+N, D-curve 16 A, 400 V AC. 15 kA IEC 60947-2.
