It's rated 10 kA breaking capacity per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC, with a DC rating of 60 V.
The D-curve trips magnetically between 10× and 20× In, so it's the right choice for circuits feeding motors, welding equipment, or large power supplies that pull a brief, high startup current.
This is a standard catalogue item in the SENTRON 5SJ4 family.
The part is halogen-free and silicon-free, and is designed for mechanical engineering and industry environments. Standard Siemens documentation includes CE declaration and RoHS/REACH compliance data available on request.
