It breaks fault currents up to 10 kA per IEC/EN 60898-2 and 15 kA per IEC 60947-2 at DC, making it suitable for branch-circuit protection in commercial and light-industrial panels. The C-curve (5-10x In) handles moderate inrush from motor starters and lighting ballasts without nuisance trips — it's the standard choice for general-purpose loads where the start-up surge isn't extreme. ## DIN-rail fit and panel integration Occupies 1 modular width unit (18 mm) on the DIN rail, with a 70 mm installation depth and 76 mm overall depth. The quick-assembly fastening system clips onto standard 35 mm DIN rail; mounting position is unrestricted. Combined terminals top and bottom accept copper conductors — no neutral pole to land, since this is a 1-pole device without neutral switching. IP20 with connected conductors means it's protected against finger contact in a closed panel, but not against dripping water; keep it inside a gland-plated enclosure. ## Breaking capacity and coordination Rated breaking capacity of 10 kA at 400 V AC per IEC/EN 60898-2, and 15 kA at DC per IEC 60947-2. The higher DC figure matters when this breaker is used in DC auxiliary circuits — say, control power from a 220 V DC bus — where fault currents can be stiffer than the AC rating suggests. Energy limitation class 3 means it limits let-through energy enough to protect downstream wiring and connected devices in most panel layouts. Overvoltage category III and pollution degree 3 suit it for fixed installations within building distribution boards, not for outdoor or wet locations. ## Sourcing and availability The 5SY5102-7 is an active, in-production Siemens SENTRON MCB. It is sourced and quoted to order through independent distribution against an RFQ — availability and current pricing are confirmed at quote time. For BOM-freeze or project-bid quantities, submit an RFQ; the supply channel covers standard catalog volumes without lead-time surprises.","metaTitle":"Siemens SENTRON 5SY5102-7 MCB, C-Curve, 1-Pole, 10kA","metaDescription":"Siemens SENTRON 5SY5102-7 miniature circuit breaker, C characteristic, 1-pole, 10 kA breaking capacity per IEC/EN 60898-2.
