The 5SJ4315-8HG41 is a 3-pole miniature circuit breaker from the Siemens SENTRON 5SJ4 series, rated at 1.6 A with a D tripping characteristic. On a 400 V AC supply, it clears faults at 10 kA per EN 60898 and 15 kA per IEC 60947-2, which gives the panel designer headroom for higher available fault current without cascading upstream.

It is rated 10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC, providing selectivity headroom for downstream sub-circuits.
Both are 3-pole DIN-rail MCBs from the SENTRON family, sharing the same 54 mm width and 90 mm height. The 5SJ4315-8HG41 is a 1.6 A D-curve; the 5SJ6216-6 is a 16 A B-curve. Panel cutout and busbar spacing are identical, but the D-curve vs B-curve difference means the 5SJ4315-8HG41 is suited for motor-starting or transformer loads, not general lighting or receptacle circuits where the 5SJ6216-6 would be used.
