The Siemens 5SL7104-8RC is a 1-pole miniature circuit breaker rated 240/415 V with a 15 kA interrupting capacity and a D-curve trip characteristic at 4 A. The D-curve (10–20× In) is designed for loads with high inrush currents — motor starters, small transformers, solenoid valves — where a B- or C-curve would nuisance-trip on startup. The 15 kA breaking capacity at 415 V gives headroom for high-fault installations without cascading upstream breakers.
