Product details

The 18 mm width (one modular unit) snaps onto a DIN rail using the quick-assembly system, and the combined top/bottom terminals accept both busbar and conductor connections without extra hardware.

At 40 °C ambient the breaker derates to 5.56 A; at 50 °C it's 5.08 A. Under UL 1077 (supplementary protector) it's rated 5 kA, so if your job spec calls for a UL 489 listed branch breaker, this is a supplementary device, not a service entrance breaker.

The quick-assembly system lets you gang multiple breakers on a busbar without extra bridging links. IP20 with connected conductors keeps it inside a panel only — not for wet or washdown locations.

Frequently asked questions

Where can I buy 5SY7106-8CC and how is it quoted?

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

What is the closest functional alternative — 5SY4106-7CV?

The 5SY4106-7CV is a 1-pole 6 A C-curve MCB in the same SENTRON family. The key difference is the trip characteristic: D-curve (10–20× In) vs C-curve (5–10× In). If your load has moderate inrush (motors, transformers), the D-curve of the 5SY7106-8CC is the right choice; for general-purpose or resistive loads the C-curve may suffice. Both share the same 18 mm width, DIN-rail mount, and 30 kA IEC breaking capacity, so they are mechanically interchangeable but not electrically equivalent for coordination.

What compliance documentation does Siemens provide for 5SY7106-8CC?

The breaker carries IEC 60947-2 (30 kA) and UL 1077 / CSA C22.2 No.235 (5 kA) ratings. It is halogen-free and silicon-free. Standard Siemens documentation includes CE declaration, RoHS/REACH compliance statements, and the product datasheet.

Will 5SY7106-8CC drop into a panel specified around 5SY4106-7CV without rewiring?

Yes — both are 1-pole, 18 mm wide, DIN-rail mounted MCBs with the same SENTRON form factor and terminal design. No rewiring is needed. The only functional difference is the trip curve (D vs C), so verify that the D-curve's higher inrush tolerance matches your load's starting current profile.
