The DC 15 kA rating (IEC 60947-2) matters for battery-backed or rectifier-fed loads. For UL 1077 / CSA C22.2 No. 235 installations, the listed 5 kA applies — confirm your available fault current stays within that limit before specifying. ## Mounting and integration — DIN rail, any position, quick assembly Combined terminals top and bottom simplify busbar and outgoing wiring. ## Environmental and compliance — halogen-free, silicon-free, wide temperature range Halogen-free and silicon-free construction suits applications sensitive to outgassing — clean rooms, medical equipment, or sealed enclosures where corrosion matters. The operating temperature range spans -40 °C to 75 °C, with derating for humidity (95% RH up to 55 °C, tapering to 35% at 75 °C).","metaTitle":"Siemens 5SY7350-6 SENTRON MCB, 3P, 50 A, B-Curve, 15 kA IEC","metaDescription":"Siemens 5SY7350-6 SENTRON miniature circuit breaker, 3-pole, 50 A, B-curve, 15 kA (EN 60898) / 20 kA (IEC 60947-2).
