Product details

Panel and deployment context

The 5SY6616-8CC: Mounts via the quick-assembly system — standard DIN-rail clip, any mounting position. Combined terminals top and bottom simplify busbar and outgoing wiring. Halogen-free and silicon-free construction matters in environments where outgassing could contaminate sensitive contacts or optics.

Frequently asked questions

How do I get current pricing and availability for 5SY6616-8CC?

Submit an RFQ with your quantity and target delivery. Pricing and stock are confirmed at quote time through independent distribution channels; this page does not publish live figures.

When sourcing 5SY6616-8CC, what is the closest functional alternative — 5SY7140-8CC?

The 5SY7140-8CC is a higher-current variant (40 A) in the same 5SY6CC design family, same 4-pole D-curve footprint. It will drop into the same DIN-rail position and terminal layout without rewiring, but the 40 A rating changes the upstream protection coordination — verify the cable and busbar sizing before substituting.

What is 5SY6616-8CC's listed depth?

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

What is 5SY6616-8CC's listed width?

Width is 72 mm, which corresponds to 4 width units on a standard DIN rail.

Will 5SY6616-8CC drop into a panel specified around 5SY7140-8CC without rewiring?

Yes — same 4-pole D-curve family, same 72 mm width, same terminal layout. The swap is mechanical and electrical drop-in, but the 16 A rating (vs 40 A) means the downstream load must be within the lower current limit. No busbar or wiring changes needed.

What compliance documentation does Siemens provide for 5SY6616-8CC?

The part is rated per EN 60898 and UL 1077 / CSA C22.2 No. 235. Standard manufacturer documentation includes CE declaration, RoHS and REACH compliance data. The halogen-free and silicon-free construction is confirmed on the spec sheet.
