Its headline number is the 15 kA ultimate breaking capacity (Icu) at 400 V AC — that's the fault current it can safely interrupt without welding its contacts or rupturing the case, which matters when you're coordinating downstream protection in a panel that sees high prospective short-circuit currents. ## Where it fits Snaps onto standard 35 mm DIN rail inside a distribution board or control cabinet. The C-curve (5–10× In magnetic trip) suits it for protecting general-purpose circuits with moderate inrush — think control transformers, contactor coils, or small motor loads where a B-curve would nuisance-trip on startup. ## Lifecycle and sourcing Listed as current-production lifecycle stage. That means the factory is still making it and the supply chain is standard — no last-time-buy clock ticking. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.","metaTitle":"5SY4614-7CV MCB, 3P+N, C0.3, 15kA Icu at 400V","metaDescription":"5SY4614-7CV miniature circuit breaker, 3P+N, C0.3 curve, 15kA breaking capacity at 400V.
