The B-curve (tripping characteristic class B) means the magnetic trip activates between 3 and 5 times rated current — 30 to 50 A for this 10 A unit. That suits resistive or lightly inductive loads like lighting circuits, socket outlets, and general-purpose branch protection where inrush is modest. If you are protecting motor circuits or transformers with higher inrush, a C-curve (like the 5SL6120-7) would be the correct choice to avoid nuisance tripping. In a multi-pole assembly, that heat adds up — for a 10-way board you are looking at roughly 16 W total from these breakers alone, which should be within the thermal budget of a standard metal enclosure without forced ventilation. Degree of pollution 2 and overvoltage category III are the standard assumptions for fixed-wiring distribution boards. The breaker is sealable, halogen-free, and silicon-free — relevant if the panel is destined for a clean room or a corrosive environment.

Frequently asked questions
Where can I buy the 5SL6110-6?
This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock or price figures are listed here.
What is the difference between the 5SL6110-6 and the 5SL6120-7?
Both are 1-pole SENTRON MCBs with the same dimensions (18 mm wide, 76 mm deep), same 6 kA breaking capacity, and same voltage ratings. The deciding factor is the tripping curve: the 5SL6110-6 is a B-curve (magnetic trip at 3–5× In), while the 5SL6120-7 is a C-curve (5–10× In). If your load has higher inrush — small motors, transformers, fluorescent banks — the C-curve is the correct fit. For resistive or general-purpose branch circuits, the B-curve is adequate and cheaper.
Will the 5SL6110-6 drop into a panel specified for the 5SL6120-7 without rewiring?
Yes, physically it is a drop-in replacement — same 18 mm width, same 76 mm depth, same DIN-rail mounting, same terminal layout. The only difference is the tripping characteristic. If the original design called for a C-curve, swapping to a B-curve may cause nuisance tripping on loads with higher inrush. Verify the load type before substituting.
What compliance documentation is available for the 5SL6110-6?
As a standard Siemens SENTRON MCB, it carries CE marking, complies with EN 60898 and IEC 60947-2, and is rated for overvoltage category III, degree of pollution 2. The product is halogen-free and silicon-free. Specific RoHS/REACH declarations are available from Siemens on request.
