The 10 kA SCCR at 400 V matches the typical fault level at the service entrance or sub-distribution board; upstream coordination with a higher-rated main breaker or fuse is the standard selectivity practice. ## Thermal derating and ambient range Rated 16 A at 30 °C ambient, the 5SN4316-7CN derates to 15.15 A at 40 °C, 14.71 A at 45 °C, 14.26 A at 50 °C, and 13.79 A at 55 °C. In a sealed enclosure or near heat-generating equipment, the 40 °C figure governs the practical load — a 15 A continuous load is the safe limit in a 40 °C panel. Snap-on DIN rail mount, any position. Installation depth 70 mm, overall depth 76 mm — the extra 6 mm accounts for the terminal screws and wire bend radius.","metaTitle":"Siemens 5SN4316-7CN SENTRON MCB, 3P, C, 16 A, 10 kA","metaDescription":"Siemens SENTRON 5SN4316-7CN miniature circuit breaker, 3-pole, C-curve, 16 A, 400 V AC, 10 kA breaking capacity per EN 60898.
