The D curve means this breaker is designed for loads with high inrush currents — typically motor circuits, transformers, or other inductive loads where the startup surge exceeds what a B or C curve would tolerate without nuisance tripping. The 6 kA breaking capacity at 230 V is the maximum fault current it can safely interrupt under standard conditions; for most residential and light commercial distribution boards this is sufficient, but verify the prospective short-circuit current at the point of installation. ## Lifecycle and Sourcing Reality RoHS compliance is confirmed since 01-06-13, and REACH candidate-list information is available on request. ## Panel Integration and Deployment The 1+N-pole format (switched phase plus switched neutral) is common in single-phase distribution boards where the neutral must be disconnected for isolation — typical in residential or light commercial final subcircuits. Mounts on standard DIN rail in the enclosure; the D curve suits motor or lighting contactor feeds where inrush is above the C-curve threshold.","metaTitle":"Siemens 5SL6503-8CC Miniature Circuit Breaker, 1+N Pole, D C","metaDescription":"Siemens 5SL6503-8CC miniature circuit breaker, 1+N-pole, D curve, 3 A, 230 V, 6 kA.
