The 3 A rating sets the continuous current it carries without tripping — size it for the load, not the wire. ## Panel integration The single-pole width (18 mm per modular unit) fits into any SENTRON distribution board or enclosure. Terminal capacity and tightening torque follow the 5SL series standard — use the datasheet for the exact wire range and torque spec before terminating.","metaTitle":"Siemens 5SL5103-7RC SENTRON MCB, 1P DC, 3A C-Curve, 10kA","metaDescription":"Siemens SENTRON 5SL5103-7RC miniature circuit breaker, 1-pole, 220 V DC, 10 kA breaking capacity, C-curve, 3 A.

Availability and current pricing are confirmed at quote time for any volume."},{"question":"What is the closest functional alternative to 5SL5103-7RC?","answer":"The 5SL3116-6MB is a 1-pole SENTRON MCB with a B-curve and 16 A rating, but it is an AC-rated unit (400 V AC, 4.5 kA) with a 72 V DC maximum — it does not match the 220 V DC rating of the 5SL5103-7RC. For a DC circuit at 3 A, the 5SL5103-7RC is the correct choice; the 5SL3116-6MB is not a functional substitute for this DC application."},{"question":"What is the design of pole and number of poles on 5SL5103-7RC?","answer":"The design of pole is 1P, and the number of poles is 1 — a single-pole breaker that switches one DC line."},{"question":"Will 5SL5103-7RC drop into a panel specified around 5SL3116-6MB without rewiring?","answer":"Physically yes — both are 1-pole SENTRON 5SL series breakers on the same DIN-rail footprint. Electrically no: the 5SL5103-7RC is a 3 A DC breaker, while the 5SL3116-6MB is a 16 A AC breaker. You would need to verify the circuit voltage (DC vs AC) and load current before substitution."},{"question":"What compliance documentation does Siemens provide for 5SL5103-7RC?","answer":"As a SENTRON product, the 5SL5103-7RC is manufactured under Siemens quality systems. Specific compliance declarations (CE, UKCA, RoHS, REACH) are typically included in the product documentation package available from Siemens.
