Width is 18 mm — one modular width unit — so it occupies a single 18 mm slot on a DIN rail. Mounting position is any — vertical, horizontal, upside-down — so it fits tight gland-plate layouts where orientation isn't fixed. IP20 with connected conductors means the terminals are finger-safe once wired; no extra cover needed inside a closed panel.

Frequently asked questions
What is 5SY5116-7KK11's listed depth?
Depth is 76 mm, with an installation depth of 70 mm. Width is 18 mm (1 MWU), height is 90 mm.
Will 5SY5116-7KK11 drop into a panel specified around 5SY5240-7?
Both are 1-pole SENTRON MCBs in the same 18 mm footprint, so the mechanical fit is identical — same DIN-rail slot, same terminal spacing. The electrical difference is the rating: 5SY5116-7KK11 is a 16 A C-curve; the 5SY5240-7 is a higher-current variant. If the panel was wired for 16 A, the 5SY5116-7KK11 is a direct drop-in without rewiring.
What compliance documentation does this brand provide for 5SY5116-7KK11?
The product is designed for railway applications and carries vibration resistance per IEC 60068-2-6. It is halogen-free and silicon-free. Standard documentation includes the manufacturer's declaration of conformity to EN 60898 and IEC 60947-2; RoHS and REACH compliance is typical for Siemens SENTRON products, though specific certificates should be requested with the RFQ.
