SENTRON 5SL4416-6 — 4-pole B-curve MCB at 16 A
The Siemens SENTRON 5SL4416-6 is a 4-pole miniature circuit breaker rated 16 A with B tripping characteristic, designed for 400 V AC multi-phase circuits. Its 10 kA breaking capacity is certified under both EN 60898 and IEC 60947-2 — meaning it can safely interrupt fault currents up to 10 kA at the rated voltage without upstream device damage. That dual-standard rating covers residential/infrastructure installations (EN 60898) and industrial panel applications (IEC 60947-2), so the same part serves both a distribution board and a control cabinet. The B-curve trips at 3–5× rated current (48–80 A magnetic release), which makes it the standard choice for resistive and general-purpose loads — lighting circuits, small heaters, control transformers — where inrush is modest. For motor or transformer circuits with higher inrush, a C-curve sibling would be specified instead.
