Siemens 5SY series, MCB, Icu=15kA at 400V, 3-pole + neutral, D-curve 6A, 5SY4606-8CV.
For a 3P+N configuration, this covers three-phase loads plus the neutral conductor, common in European-style distribution boards where the neutral is switched alongside the phases.
The 3P+N format fits sub-distribution boards feeding three-phase motor groups or mixed single-phase/three-phase loads where neutral isolation is required. The D6 rating handles sustained loads up to 6 A per phase, so size it for the branch circuit, not the main incomer.
The ultimate short-circuit breaking capacity Icu is 15 kA at 400 V, as stated in the product description.
The D-curve trips at 10–20 times the rated current (6 A), so it tolerates high inrush from motors, transformers, or capacitive loads without nuisance tripping.
