The Siemens 5SL4314-8CC is a 3-pole miniature circuit breaker rated at 400 V with a 10 kA breaking capacity, D-curve trip characteristic, and a 0.3 A current rating. This is a DIN-rail mounted device from the Basic Devices family, intended for branch-circuit overcurrent protection in distribution panels and control cabinets where the D-curve's high inrush tolerance is needed — typically for motor loads, transformers, or lighting with heavy starting currents.
