The Siemens 5SL6563-8CC is a 1+N-pole miniature circuit breaker rated 230 V with a 6 kA breaking capacity, D tripping characteristic, and 63 A current rating — a standard panel-protection device for the 5SL6 Basic Devices family.
What the ratings mean for fit
The D-curve characteristic (10–20× In magnetic trip) is designed for loads with high inrush currents — motor starters, transformers, or lighting ballasts — where a B or C curve would nuisance-trip on startup. At 63 A continuous rating, this MCB protects a branch circuit feeding a moderate motor or a sub-distribution board. The 6 kA breaking capacity at 230 V is adequate for most residential and light commercial panelboards where the prospective short-circuit current stays under that threshold. The 1+N-pole configuration switches the line conductor and provides neutral disconnection, which is required in some regional wiring codes (e.g., UK, Australia) for single-phase final circuits. The neutral pole is a switching neutral, not a fully rated pole — it breaks the neutral but does not provide overcurrent protection on that leg.
Lifecycle and compliance
RoHS compliance is confirmed since June 2013, and the manufacturer publishes REACH candidate-list information on request. The export control classification is AL: N / ECCN: N — no special license required for cross-border trade.
Sourcing and procurement
Product class B means this item carries a restricted return policy — Siemens directs returns to its partner channel rather than accepting direct returns from end users. For a BOM-line commitment, we source this active order code through our independent distribution network and quote it to order against an RFQ. Availability and current pricing are confirmed at quote time.
