The Siemens 5SL6208-8CC is a 2-pole miniature circuit breaker rated 400 V with a 6 kA breaking capacity and a D tripping characteristic at 8 A. This is a DIN-rail mounted MCB from the Basic Devices family, designed for branch-circuit protection in distribution boards and control panels. The D-curve (10–20× In) suits loads with high inrush currents — typically motor starters, small transformers, or discharge lighting — where a B or C curve would nuisance trip on startup.
Sourcing and lifecycle
Lifecycle status is Active per Siemens. This is a current-production part, not subject to phase-out or last-time-buy. For BOM freeze or PCN watch purposes, the part carries Group Code P310 and Product Group 3821 — these are Siemens internal classification codes used to track family-level changes. No official successor exists because the part is still in the active catalogue. Supply is quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
