For DC circuits, the interrupting capacity is 15 kA at 60 V per IEC 60947-2, and under UL 1077 it is 5 kA — useful if the panel also sees North American supplementary protection requirements. ## Type A trip: when it matters The tripping characteristic is Type A, which means the magnetic trip threshold is between 2 and 3 times In. That is tighter than a Type B (3–5× In) or Type C (5–10× In). Type A is specified for semiconductor protection or circuits with sensitive electronics where you need fast magnetic trip on moderate overcurrents without nuisance tripping from inrush. It is less common than B or C, so if the BOM calls for Type A, this is the exact fit. ## Physical fit and DIN-rail integration The fastening system uses a quick-assembly clip — no tools needed to snap it on or off. The terminals are combined (top and bottom), accepting both busbar and wire. ## Environmental and compliance specs The breaker is sealable, which allows panel builders to lock the toggle position after commissioning.","metaTitle":"Siemens 5SY4325-5 3-Pole MCB, 10 kA EN 60898, Type A","metaDescription":"Siemens 5SY4325-5 SENTRON 3-pole MCB, 400 V AC, 10 kA (EN 60898), Type A trip, 3 MW units.
