Panel fit and trip curve
The Siemens 5SY7625-6 is a 4-pole (3P+N) SENTRON miniature circuit breaker with a B-curve trip characteristic, rated 400 V AC. The B-curve trips between 3 and 5 times rated current — standard for general-purpose resistive and light inductive loads where nuisance tripping from inrush isn't a concern. The 4-module-width (72 mm) body snaps onto any DIN rail; the quick-assembly system and combined top/bottom terminals mean you can busbar it without extra comb-bridge adapters. Depth is 76 mm, installation depth 70 mm — fits standard distribution boards without a deep enclosure.
Breaking capacity and dual-standard rating
Rated 15 kA per EN 60898-1 and 25 kA per IEC 60947-2 — the higher figure under the industrial standard means this breaker handles fault currents up to 25 kA at 400 V AC in an industrial panel. The DC rating is 15 kA at 60 V (max 72 V) per IEC 60947-2, and UL 1077 recognition at 5 kA covers North American installations. That dual-standard compliance (IEC/EN 60898-1 + IEC 60947-2 + UL 1077) simplifies BOM consolidation across regions.
Lifecycle and sourcing
Listed as current production — no phase-out notice on this order code. The 5SY7625-6 is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. For a BOM freeze, this is a stable line with no imminent LTB.
Environmental and compliance
Halogen-free and silicon-free construction, rated for pollution degree 3 and overvoltage category III. Operating temperature range -40 °C to 75 °C with humidity derating above 55 °C. IP20 with connected conductors — standard for enclosed distribution boards. Neutral conductor is switched (3P+N), and the supply cord position is any, which simplifies wiring in tight enclosures.
