The Siemens 5SL5816-7 is a 2-pole miniature circuit breaker rated for 16 A with a C-trip curve and a 6 kA interrupting capacity at 110 V DC. It fits a single module width (18 mm) on a DIN rail, making it a direct swap into standard distribution boards or sub-panels where DC branch protection is needed. The C-curve means it trips between 5 and 10 times rated current — suited for moderate inrush loads like small DC power supplies or control transformers, not for high-surge motor starts. At 110 V DC, the 6 kA breaking capacity covers most commercial and light industrial fault levels; verify the prospective short-circuit current at the point of installation stays under that threshold.
