Product details

The Siemens 5SY5416-6 is a SENTRON miniature circuit breaker with a B tripping curve and four poles, rated for 400 V AC and 880 V DC. The 10 kA breaking capacity under IEC/EN 60898-2 and the additional 15 kA DC rating per IEC 60947-2 tell you it can safely interrupt fault currents up to those levels without upstream cascading. Mounts on a DIN rail via the quick-assembly system, fitting a standard 72 mm wide footprint (4 modular width units) with 70 mm installation depth.

Deployment context

The 72 mm width (4 MW) and 76 mm depth mean it slots into standard DIN-rail backboards; account for the 70 mm installation depth when sizing gland plates. The sealable option matters for lockout/tagout procedures in industrial panels.

Frequently asked questions

Where can I buy 5SY5416-6 and how do I get a price?

The part is sourced and quoted to order against an RFQ through independent distribution. Submit a request for quote (RFQ) to confirm availability and current pricing.

When sourcing 5SY5416-6, what's the closest functional alternative?

The 5SY5416-7 is a peer variant that shares the same 4-pole B-curve 16 A core ratings and overall dimensions (72 mm wide, 76 mm deep). The key difference is the tripping characteristic: the -6 uses a B-curve (3-5x In), while the -7 uses a C-curve (5-10x In), making the -7 better suited for moderate inrush loads like small motors or transformers. Panel fit is identical — no rewiring needed if the application can tolerate the different curve.

What compliance documentation does Siemens provide for 5SY5416-6?

The breaker carries IEC/EN 60898-2 and UL1077 approvals, and is halogen-free and silicon-free, which supports RoHS and REACH declarations. Manufacturer documentation typically includes a declaration of conformity and the UL file number.
