The D-curve means it tolerates high inrush currents — typically found on motor, transformer, or welding loads — without nuisance tripping on startup, while still clearing a hard fault within the 6 kA short-circuit rating. This part snaps onto standard DIN rail in a distribution board or industrial panel. The 400 V rating covers three-phase line-to-line applications common in European and IEC-based installations. The 6 kA breaking capacity is sufficient for most final subcircuits in commercial and light industrial buildings, but verify the prospective fault current at the point of installation — if your panel's SCCR exceeds 6 kA, you need an upstream current-limiting device or a higher-rated breaker. ## Lifecycle and sourcing posture The manufacturer lists this part as current production — no end-of-life notice or last-time-buy window has been issued. The RoHS compliance date is June 2013, confirming it has been lead-free since that batch. REACH candidate-list disclosure is available on request from Siemens. The product class is marked B — return restricted, meaning Siemens controls the reverse logistics. For procurement, this is a standard active line item sourced through authorized distribution; availability and current pricing are confirmed at quote time against an RFQ. No pin-compatible alternative exists within the same Siemens family — the 5SL6 series is the current-generation platform. ## Panel integration and compliance notes Mounts on 35 mm DIN rail per EN 60715. The 3-pole footprint occupies three modular width units (17.5 mm per pole). Terminal capacity accepts up to 25 mm² conductor for line and load sides. The D-curve characteristic means this breaker is sized for loads with a high let-through energy on startup — typically motors, drives, or discharge lighting — not for resistive or general-purpose circuits where a B or C curve would suffice. Export control classification is AL: N / ECCN: N, meaning no special licensing is required for cross-border shipment under current regulations. The group code P310 and product group 3821 are Siemens internal cataloging fields that help with cross-reference in legacy BOMs but do not affect fit or function.","metaTitle":"Siemens 5SL6350-8CC MCB, 3-pole D 50A, 400V 6kA","metaDescription":"Siemens 5SL6350-8CC miniature circuit breaker, 3-pole, D-curve, 50 A rated, 400 V AC, 6 kA breaking capacity.
