The Siemens 5SL4106-8CC is a 1-pole miniature circuit breaker rated 230/400 V with a 10 kA breaking capacity and a D-curve trip characteristic at 6 A. The D-curve means it tolerates the high inrush currents typical of motor and transformer loads — it trips between 10× and 20× rated current, so it won't nuisance-trip on a motor start but clears a hard fault fast. That 10 kA SCCR at 400 V is the interrupting capacity per IEC 60898; it safely clears a bolted fault up to that level without welding the contacts or cascading upstream.
Sourcing and lifecycle
Lifecycle status is Active per Siemens — this is a current-production catalog number, not a phase-out or NRND line. For BOM-freeze or volume planning, it is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. The product class is B (return restricted), so any return or credit requires prior Siemens partner coordination — factor that into your procurement process.
Compliance documentation
RoHS compliant since 01-06-13. REACH Article 33 duty to inform applies: lead (CAS 7439-92-1) is present above 0.1% w/w in the candidate list. Export control is AL:N / ECCN:N — no license required for standard industrial use. No UL or CSA listing is on record for this specific order code; verify with your Siemens contact if a UL 489 mark is required for your panel.
Panel integration
Snap-on DIN rail mount to EN 60715. Single-pole width (1 module at 17.8 mm). The D-curve and 6 A rating suit it for a motor control panel protecting a small pump or fan circuit where the inrush exceeds a C-curve's tolerance. Terminal capacity accepts up to 25 mm² conductor; torque to 2.5 Nm.
