The Siemens 5SL4463-8CC is a 4-pole miniature circuit breaker from the Basic Devices series, rated 400 V with a 10 kA interrupting capacity and a D tripping characteristic at 63 A. The D curve provides a high magnetic trip threshold (10–20× In), making it suitable for loads with high inrush currents such as motor starters, transformers, and discharge lighting — common in industrial panel builds where selectivity with downstream breakers is a design requirement.
