The Siemens 5SL5820-7 is a 2-pole miniature circuit breaker from the Basic Devices family, rated 20 A with a C-characteristic trip curve and a 6 kA interrupting capacity at 110 V DC. The C-curve means it trips between 5 and 10 times rated current — suited for moderate inrush loads like small motors or lighting panels where you need some short-time delay against startup peaks without sacrificing branch-circuit protection. At 1 MW (18 mm) wide, it fits standard Siemens distribution boards and can be ganged with other 5SL5 series breakers for multi-pole configurations.
