The Siemens SENTRON 5SL4413-8 is a 4-pole miniature circuit breaker (MCB) with a D tripping characteristic, rated 13 A at 400 V AC. It occupies 4 modular width units (72 mm) on a DIN rail and carries a 10 kA breaking capacity per both EN 60898 and IEC 60947-2 — meaning it can safely interrupt a fault current up to 10,000 A without welding its contacts or cascading the fault upstream. The D-curve (10–20× In magnetic trip) is sized for loads with high inrush, typically small transformers, welding equipment, or motor circuits where the start-up surge would nuisance-trip a B or C curve.
Fit and panel integration
Mounts on a standard 35 mm DIN rail in any orientation — no derating needed for horizontal or inverted installation. The 72 mm width (4 MW) matches the 4-pole footprint; verify your enclosure's spare module positions before committing the BOM line. IP20 with connected conductors, so it's suitable for enclosed distribution boards in residential and infrastructure builds. Sealable terminals (padlockable) for lockout/tagout compliance. Installation depth is 70 mm, overall depth 76 mm — check clearance behind the DIN rail for wiring bends.
Ratings and what they mean for selection
Breaking capacity: 10 kA at 400 V AC per EN 60898 (the household-and-similar standard) and the same 10 kA per IEC 60947-2 (the industrial standard). That's a single rating that satisfies both compliance frameworks — no split between domestic and industrial SCCR values. Operating voltage max is 440 V AC multi-phase, so it covers 400/415 V three-phase networks with headroom. The 50/60 Hz rating covers both line frequencies globally. Power loss per pole is 1.4 W at rated current in hot state — 5.6 W total for the 4-pole assembly at full load, relevant for thermal budgeting in a sealed enclosure. Ambient range: -40 °C to +75 °C, covering cold storage and rooftop cabinets. Pollution degree 2 (normal, non-conductive), overvoltage category III (fixed installation downstream of the main distribution board).
