Product details

Integration and mounting

Mounts on DIN rail via the quick assembly system in any position. Occupies 4 modular width units — that's 72 mm width on the rail. Depth is 76 mm, with an installation depth of 70 mm behind the panel surface. Height is 90 mm. The combined terminal top and bottom accept conductors from either direction, simplifying busbar routing. IP20 with connected conductors — protected against finger touch but not moisture, so install inside a rated enclosure. Overvoltage category III and pollution degree 3 suit fixed installations in industrial environments where transient overvoltages are common.

Frequently asked questions

Where can I buy 5SY4416-7KK11 and how do I get a price?

This part is available to order through independent distribution. Submit an RFQ; availability and current pricing are confirmed at quote time. No stock count or price is listed here.

What is the breaking capacity of 5SY4416-7KK11?

10 kA per EN 60898 and 20 kA per IEC 60947-2. Use the IEC 60947-2 figure for industrial panel SCCR calculations.

Will 5SY4416-7KK11 drop into a panel specified around 5SY4140-7 without rewiring?

Both are 4-pole SENTRON MCBs on the same DIN-rail footprint (4 MW, 72 mm wide). The 5SY4416-7KK11 is a 16 A C-curve; the 5SY4140-7 is a 40 A C-curve. If the panel busbars and load wiring are sized for 40 A, installing a 16 A breaker is fine — the breaker protects downstream, not upstream. No rewiring of the rail or terminals is needed.
