The 5SY8314-7 is a SENTRON 3-pole miniature circuit breaker with a C tripping characteristic, rated at 400 VAC and delivering 70 kA interrupting capacity per IEC 60947-2 — that's the fault-clearing figure that governs the arc-flash rating downstream. At DC it holds 15 kA per the same standard; under UL 1077 it's listed at 5 kA, so for a UL 508A panel the branch-circuit SCCR must stay at or below that limit. Mounting position is any. Depth is 76 mm (70 mm behind the panel surface). Vibration resistance per IEC 60068-2-6 is ±1 mm at 5 to 25 Hz and 50 m/s² at 25 to 150 Hz — it holds up on a mill table or conveyor drive panel without nuisance trips from mechanical shock.
