Product details

The 5SL5103-7RC: The 10 kA breaking capacity at 220 V DC means this breaker can safely interrupt a fault current up to 10,000 A on a DC circuit — essential for protecting downstream wiring and loads in DC distribution panels, battery banks, or solar combiner boxes. 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.

Frequently asked questions

Who supplies 5SL5103-7RC and how is it quoted for volume purchases?

This part is sourced through independent distribution channels and is quoted to order against an RFQ. Availability and current pricing are confirmed at quote time for any volume.

What is the closest functional alternative to 5SL5103-7RC?

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.

What is the design of pole and number of poles on 5SL5103-7RC?

The design of pole is 1P, and the number of poles is 1 — a single-pole breaker that switches one DC line.

Will 5SL5103-7RC drop into a panel specified around 5SL3116-6MB without rewiring?

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.

What compliance documentation does Siemens provide for 5SL5103-7RC?

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. The evidence does not list individual certs for this order code.
