The 5SJ4115-7HG40: The C-curve (tripping between 5 and 10 times rated current) is the standard choice for inductive and motor-starting loads where inrush is moderate — pumps, fans, small conveyors. The 10 kA EN 60898 rating is the residential/commercial ceiling; the 15 kA IEC 60947-2 rating is the one that matters for industrial panel SCCR compliance. Single-pole means it switches only the line conductor — no neutral switching, so it is used in single-phase branch circuits or as a pole in multi-pole assemblies.

Frequently asked questions
Where can I buy 5SJ4115-7HG40 and get a price?
This part is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time.
What is the closest functional second-source to 5SJ4115-7HG40?
The 5SY4116-7CV is a single-pole C-curve MCB in the same SENTRON family, but it carries a different breaking capacity rating and may have a different rated current. Verify the specific ratings against your application before substituting — they are not drop-in interchangeable without checking the branch-circuit SCCR.
Will 5SJ4115-7HG40 drop into a panel specified around 5SY4116-7CV without rewiring?
Both are 1-pole, 18 mm wide DIN-rail mount, so the mechanical fit and terminal positions are identical. The electrical ratings differ — confirm the breaking capacity and rated current of each against your fault study before swapping. No rewiring needed if ratings match.
