It is built for overcurrent and short-circuit protection in residential and infrastructure AC circuits up to 400 V. ## Breaking capacity and coordination Rated breaking capacity is 6 kA according to EN 60898 at 400 V AC. This is the standard for most domestic and light commercial distribution boards. The C-curve (5–10× In) handles moderate inrush from motor starters and fluorescent lighting without nuisance tripping. Energy limitation class 3 means it limits let-through energy during a fault, aiding downstream selectivity. Overvoltage category III and pollution degree 2 suit fixed installation in the main distribution panel. ## Integration and mounting Occupies 3 modular width units (54 mm) on a DIN rail. Depth is 76 mm, installation depth 70 mm. Mounting position is any — no derating for horizontal or vertical orientation. IP20 with distribution board cover, so it requires an enclosure for exposed installations. Halogen-free and silicon-free construction, sealable for tamper-proof installations. Mechanical service life is 10 000 operating cycles typical. No supplementary devices (auxiliary contacts, shunt trips) can be installed on this variant.","metaTitle":"Siemens 5SL6306-7YA SENTRON MCB, 3P C 6A 6kA","metaDescription":"Siemens 5SL6306-7YA SENTRON miniature circuit breaker, 3-pole, C-curve, 6 A, 6 kA breaking capacity per EN 60898 at 400 V AC.
