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.

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.
Depth is 76 mm; installation depth (behind the panel face) is 70 mm.
Width is 72 mm, which corresponds to 4 width units on a standard DIN rail.
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.
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.
