The 1P+N pole design switches both line and neutral, with the neutral pole switching but not protecting — useful where neutral isolation is needed without overcurrent detection on the neutral path. Breaking capacity is rated 10 kA per EN 60898-1 for standard household/commercial branch circuits, and 35 kA per IEC 60947-2 for industrial panel duty — the higher figure applies when the MCB is installed upstream of a transformer or in a high-fault location. Under UL 1077 the rating is 5 kA, which governs North American supplementary protection applications. For DC circuits the part is rated 15 kA at up to 72 V, so it can serve as a DC branch protector in control panels or solar combiner boxes, not just AC distribution. ## Mounting and panel integration The 5SY4506-8 snaps onto a DIN rail via the quick assembly system and occupies 2 modular width units (36 mm). Depth is 76 mm, installation depth 70 mm — check gland plate clearance if back-panel wiring is tight. Mounting position is any, so vertical or horizontal DIN-rail orientation works. IP20 with connected conductors — fine inside a closed panel, not for washdown or outdoor exposure. Pollution degree 3 and overvoltage category III suit industrial environments with conductive dust or transient surges.","metaTitle":"Siemens 5SY4506-8 SENTRON MCB, D Curve, 1P+N, 10 kA","metaDescription":"Siemens 5SY4506-8 SENTRON miniature circuit breaker, D tripping characteristic, 1P+N, 10 kA per EN 60898-1, 35 kA per IEC 60947-2.
