Breaking capacity is 15 kA per EN 60898 and 40 kA per IEC 60947-2, with a 5 kA rating under UL 1077 / CSA C22.2 No. 235. That 40 kA IEC figure gives you headroom for high-fault installations; the 15 kA EN rating covers the standard domestic/commercial panel spec. ## Mounting and wiring — panel fit Touch protection is built in; the unit is sealable. Ambient range -40 to +75 °C operating, storage -40 to +70 °C. Halogen-free and silicon-free construction, so it won't outgas corrosive compounds in sensitive environments like data centers or medical equipment. Suitable for mechanical engineering and industrial applications per the manufacturer. Overvoltage category III, pollution degree unspecified but typical for this class. Compliance with EN 60898 and IEC 60947-2 is listed; UL 1077 / CSA C22.2 No. 235 recognized for the 5 kA AC rating. The product is classified as F per DIN EN 61346-2 and DIN EN 81346-2.","metaTitle":"Siemens 5SY7606-8 SENTRON MCB, 6 A, D Curve, 4P, 15/40 kA","metaDescription":"Siemens 5SY7606-8 SENTRON miniature circuit breaker, 6 A rated, D tripping characteristic, 4-pole (3P+N), 400 V AC, 15 kA (EN 60898) / 40 kA (IEC 60947-2).
