The Siemens 5SJ4208-8HG41 is a 2-pole miniature circuit breaker from the SENTRON 5SJ4 series, with a D tripping characteristic. It breaks 10 kA per EN 60898 for general distribution and 15 kA per IEC 60947-2 for industrial panel duty; the higher figure is the one to use for SCCR coordination in a machine control panel. Rated 400 V AC and 60 V DC, so it covers single-phase and line-to-line loads in 230/400 V networks, plus DC control circuits up to 60 V.

Frequently asked questions
What is the breaking capacity of 5SJ4208-8HG41?
10 kA per EN 60898 for general distribution; 15 kA per IEC 60947-2 for industrial panel duty. The IEC 60947-2 figure governs SCCR coordination in machine control panels.
Will 5SJ4208-8HG41 drop into a panel specified around 5SY4304-7CV?
Both are 2-pole DIN-rail MCBs with similar dimensions, but the 5SY series uses a different trip-curve and breaking-capacity rating. Verify the panel's SCCR requirement and trip coordination before substituting — the 5SJ4208-8HG41 carries a D-curve and 15 kA (IEC 60947-2), which may differ from the 5SY part's rating.
Where can I buy 5SJ4208-8HG41?
