The Siemens 5SL4520-6CC is a miniature circuit breaker (MCB) from the Basic Devices family, rated 230 V with a 10 kA breaking capacity. It is a 1+N-pole unit with a B tripping characteristic and a 20 A current rating. The B curve means it trips between 3 and 5 times the rated current, making it suitable for protecting resistive and general-purpose loads like lighting circuits and small appliances in residential or light commercial panels.
