Breaking capacity is 6 kA per EN 60898 and 5 kA per UL 1077 / CSA C22.2 No. 235. That covers most industrial panel sub-feed applications where the upstream device limits fault current below those thresholds. Overvoltage category III, so it's rated for fixed-installation distribution — not just final circuits. Occupies 3 width units (54 mm). Terminals accept solid or stranded conductors from 0.75 mm² up to 35 mm² — generous for a 0.3 A breaker, useful when you need to loop through larger supply conductors. Combined terminals top and bottom; sealable for tamper-proofing.","metaTitle":"Siemens 5SY6314-8CC SENTRON MCB, 3P D 0.3 A, 6 kA","metaDescription":"Siemens 5SY6314-8CC SENTRON miniature circuit breaker, 3-pole, D-curve, 0.3 A, 400 V AC, 6 kA IEC, 5 kA UL 1077.
