Product details

Its breaking capacity is 10 kA per EN 60898 for residential/commercial branch circuits, and 15 kA per IEC 60947-2 for industrial panel duty; that 15 kA figure is the one that matters for a machine builder certifying to IEC 60947-2, since it confirms the breaker can safely clear a fault up to that level without welding contacts or cascading upstream. That 18 mm width is the critical panel-fit number — it matches the standard 1-MW slot in any SENTRON or SIRIUS distribution board, so a panel layout built around 18 mm modules will accept this breaker without re-spacing the gland plate.

The C-curve and 1-pole form factor make it a drop-in replacement for any panel originally designed around a 1-module C-curve MCB — no rewiring, no DIN-rail rework.

Frequently asked questions

Where can I buy 5SJ4106-7HG41 and what is the lead time?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm lead-time and price quote.

What is the closest second-source to 5SJ4106-7HG41?

The 5SY4116-7CV is the closest functional sibling — same 1-pole C-curve, same 18 mm DIN-rail footprint. The key difference is breaking capacity: the 5SJ4 offers 10 kA (EN 60898) / 15 kA (IEC 60947-2), while the 5SY4 typically carries 25 kA (IEC 60947-2). Choose the 5SY4 if your panel SCCR requires 25 kA; otherwise the 5SJ4 is the cost-optimized drop-in.

Will 5SJ4106-7HG41 fit a panel designed for 5SY4116-7CV without rewiring?

Yes — both parts share the same 18 mm width, DIN-rail mount, and 1-pole form factor. The terminals are in the same positions, so no rewiring or DIN-rail rework is needed for a swap.

What compliance documentation does Siemens provide for 5SJ4106-7HG41?

The part carries IEC 60947-2 and EN 60898 ratings, and the housing is halogen-free and silicon-free. Standard Siemens documentation includes a CE declaration of conformity and RoHS/REACH compliance statements available through the Siemens Industry Online Support portal.
