At DC per IEC 60947-2 it holds 15 kA, which matters if this breaker lands in a DC bus or battery circuit.
B-curve trips between 3 and 5 times rated current — 189 to 315 A at 63 A. The 63 A rating is the continuous thermal current at 50/60 Hz; at elevated ambient temperature the breaker derates per the influence curve (max 95% RH at 55 °C, dropping to 35% RH at 75 °C). Width is 18 mm — one modular unit on a standard DIN rail. Mounting position any, which simplifies tight gland-plate layouts.
The 5SL4363-7 is a peer in the same SENTRON family, but it is a different curve and pole count — verify tripping characteristic and number of poles before substituting. The 5SY6163-6 is B-curve, 1-pole; the 5SL4363-7 is a different variant. No drop-in replacement without rewiring or coordination check.
Width 18 mm, depth 76 mm, height 90 mm. Installation depth is 70 mm. Occupies one modular unit on DIN rail.
The breaker carries ratings per EN 60898 (6 kA), IEC 60947-2 (10 kA AC, 15 kA DC), UL 1077 (5 kA), and CSA C22.2 No. 235 (5 kA). It is halogen-free, silicon-free, and sealable. Touch protection is fitted. No RoHS/REACH statement is in this record, but Siemens standard declarations apply for the SENTRON line.
