This is the part you grab when the line-down call is a 50 A three-phase lighting or resistive load panel that needs fast overcurrent protection — the B curve trips at 3-5× rated current, so it clears short circuits fast enough to protect sensitive loads without nuisance tripping on mild inrush. The 54 mm width (3 width units) and 70 mm installation depth leave room alongside other SENTRON modules on the same rail; the 76 mm overall depth fits standard 80 mm deep enclosures.","metaTitle":"Siemens 5SY4350-6CC11 SENTRON MCB, 50 A, 3-Pole, B Curve, 10","metaDescription":"Siemens 5SY4350-6CC11 SENTRON miniature circuit breaker, 50 A, 3-pole, B tripping characteristic, 10 kA breaking capacity per EN 60898.
