It interrupts fault currents up to 6 kA at 400 V AC per EN 60898, which means it clears a short-circuit fast enough to protect downstream wiring in a standard commercial or light-industrial distribution board. The B-curve trips between 3 and 5 times rated current — 60 to 100 A — so it's sized for resistive and general-purpose loads where you don't want nuisance trips from modest inrush. It also carries a 5 kA interrupting rating per UL 1077 and CSA C22.2 No.235, covering North American panel builds. Humidity tolerance is specified: max 95% RH at 55 °C, derating to 35% at 75 °C. Vibration resistance per IEC 60068-2-6 at ±1 mm from 5 to 25 Hz and 50 m/s² from 25 to 150 Hz — solid for machinery-mounted panels.","metaTitle":"Siemens 5SY6320-6CC SENTRON MCB, 3P 20A B-Curve, 6kA","metaDescription":"Siemens 5SY6320-6CC SENTRON miniature circuit breaker, 3-pole, 20 A, B characteristic, 6 kA per EN 60898.

The 5SY6320-6CC is 3-pole, so it occupies three modular width units instead of one and switches all three phases simultaneously. Both share the same 6 kA breaking capacity and B-curve characteristic. If your panel was specified around the 1-pole unit, the 3-pole will not drop in without rewiring — the pole count and width are different."},{"question":"What compliance documentation is available for the 5SY6320-6CC?","answer":"The part is rated per EN 60898 (6 kA) and UL 1077 / CSA C22.2 No.235 (5 kA). It carries IEC 81346-2 and DIN EN 61346-2 designation F.
