It belongs to the 5SL5 series of DIN-rail mounted MCBs designed for DC branch circuit protection in control panels and distribution boards. ## DC rating and breaking capacity The 125 V DC rating covers common 110 V DC and 125 V DC control circuits found in switchgear, relay panels, and industrial automation. On a 125 V DC rail, this breaker clears a short-circuit fault within the rated 10 kA without cascading upstream. ## Panel integration The B3 curve is factory-set and non-adjustable; verify coordination with downstream loads before specifying. The DC rating applies only when the breaker is used in a DC circuit — AC ratings differ and are not listed for this variant.","metaTitle":"Siemens 5SL5103-6CC Miniature Circuit Breaker 125V DC 10kA B","metaDescription":"Siemens 5SL5103-6CC miniature circuit breaker, 125V DC, 10kA breaking capacity, 1-pole B3 curve.
