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. ## Sourcing reality","metaTitle":"Siemens 5SY8314-7 SENTRON MCB, 3P C-Char, 70 kA IEC, 400 VAC","metaDescription":"Siemens SENTRON 5SY8314-7 miniature circuit breaker, 3-pole C-characteristic, 70 kA interrupting capacity per IEC 60947-2, 400 VAC.
