The B curve means magnetic trip occurs between 48 A and 80 A — fast enough to clear a hard short but forgiving enough to avoid nuisance trips on moderate inrush. For DC circuits, the maximum rated voltage is 60 V, so it can serve DC sub-circuits within that limit. ## Integration — DIN-Rail Mount, 70 mm Depth, Any Position Terminal capacity of 25 mm² stranded covers incoming feeder conductors up to 4 AWG. Touch protection is integrated (product feature: Yes). Periodic exposure to +55 °C at up to 95% humidity is permissible, but continuous operation above 45 °C requires derating per the thermal curve. Vibration resistance is 50 m/s² at 25–150 Hz and 60 m/s² at 10–150 Hz per IEC 60068-2-6. ## Compliance & Standards — EN 60898, IEC 60947-2, Overvoltage Category III The dual rating means it is certified for use in residential/commercial boards (EN 60898) and industrial control panels (IEC 60947-2) — the same 6 kA figure applies in both contexts. Overvoltage category III confirms suitability for fixed-installation distribution boards downstream of the main panel. Energy limiting class 3 means the breaker limits let-through energy to a low level during a fault, reducing stress on downstream components. Mechanical service life is 20 000 switching cycles typical — adequate for branch-circuit protection where switching is infrequent (not a load-switching device).","metaTitle":"Siemens 5SJ6316-6 SENTRON MCB, 3-Pole, B Curve, 16A, 6kA","metaDescription":"Siemens 5SJ6316-6 SENTRON miniature circuit breaker, 3-pole, B characteristic, 16 A, 6 kA breaking capacity per EN 60898.
