Product details

The Siemens 5SY4516-8 is a SENTRON miniature circuit breaker with a D tripping characteristic, 2-pole design (1P+N), and a breaking capacity of 10 kA per EN 60898 or 20 kA per IEC 60947-2 at 230 V AC. It also carries a 15 kA DC rating per IEC 60947-2 at 60 V DC, and 5 kA per UL 1077. The neutral pole switches, so it's suitable for single-phase final circuits where you want to isolate both conductors.

Fit and Mounting

Sourcing and Documentation

For compliance documentation, the manufacturer provides the usual IEC/EN 60898-1 and IEC/EN 60947-2 declarations, plus UL 1077 and CSA C22.2 No. 235 certifications — all standard for this SENTRON series.

Frequently asked questions

What are the key ratings for 5SY4516-8?

Breaking capacity is 10 kA per EN 60898, 20 kA per IEC 60947-2 at 230 V AC, and 15 kA DC at 60 V DC. Tripping characteristic is D, poles are 2 (1P+N), and operating voltage is 230 V AC / 60 V DC.

Will 5SY4516-8 drop into a panel specified around 5SY4116-7CV without rewiring?

Both are 2-pole SENTRON MCBs with the same DIN-rail footprint and 36 mm width, so mechanical fit is identical. The key difference is the tripping curve — 5SY4516-8 is D curve (high inrush), while 5SY4116-7CV is B curve (general purpose). If the panel was wired for a B-curve load profile, swapping to a D curve may change protection coordination; verify the load type before substitution.

Where can I buy 5SY4516-8 and how is it quoted?
