Product details

The D curve holds through 10–20× rated current long enough for the load to settle, then clears fast on a hard short.

Breaking capacity — the number that decides panel coordination

This breaker carries three breaking-capacity ratings because it's certified under multiple standards. Per EN 60898 it's 6 kA — the residential/commercial standard. Per IEC 60947-2 it's 30 kA — the industrial standard that governs panel SCCR. There's also a DC rating of 15 kA at 72 V per IEC 60947-2, and 5 kA per UL 1077 / CSA C22.2 No. 235.

Sealable, halogen-free, silicon-free — matters for clean-room or food-grade panels where outgassing is a concern.

Environmental range and approvals

That -40 °C floor makes it viable for outdoor enclosures in cold climates — no heater needed just to keep the breaker from failing to trip.

Frequently asked questions

How do I get current pricing and availability for 5SY6106-8?

We source the 5SY6106-8 to order against an RFQ. Submit a request and we'll confirm availability and current pricing at quote time.

When sourcing 5SY6106-8, what's the closest functional second-source — 5SY4140-7?

The 5SY4140-7 is a 1-pole D-curve MCB from the same SENTRON family, but it's a 40 A device — different current rating entirely. The 5SY6106-8 is a 6 A breaker; the 5SY4140-7 is for a 40 A branch. They share the same rail footprint and terminal layout, so a panel designed for the 5SY4140-7 will physically accept the 5SY6106-8 without rewiring, but the current rating mismatch means you cannot swap them without re-coordinating the circuit protection.

What is 5SY6106-8's listed depth (76 mm) on this component line?

The overall depth is 76 mm; installation depth (behind the panel face) is 70 mm.

What is 5SY6106-8's listed width (18 mm) on this component line?

Width is 18 mm — that's 1 width unit on a DIN rail, so it occupies a single module slot.

Will 5SY6106-8 drop into a panel that was specified around 5SY4140-7 without rewiring?

Yes, physically it will — same 18 mm width, same DIN-rail quick-assembly system, same terminal layout. But electrically it's a 6 A breaker versus a 40 A breaker. You cannot simply swap them; the circuit protection must be re-coordinated for the lower rating.

What compliance documentation does this brand provide for 5SY6106-8 (RoHS, REACH, UL, IEC)?

The 5SY6106-8 carries IEC 60898 and IEC 60947-2 certifications, plus UL 1077 and CSA C22.2 No. 235 recognition. It is halogen-free and silicon-free, which aligns with RoHS/REACH material restrictions. Standard Siemens declaration of conformity and material declarations are available.
