At 40 °C ambient the continuous current derates to 59.18 A; at 55 °C it drops to 52.93 A, so if the breaker lives in a crowded enclosure or near heat sources, size up or check the thermal curve. The 18 mm width (1 MW) fits a standard DIN-rail cutout; the 76 mm depth leaves room for cable bending behind the gland plate. IP20 with connected conductors — fine for a closed panel, not for washdown. The sealable design (padlockable toggle) allows lockout/tagout without an accessory. Supplementary devices (auxiliary contacts, shunt trip, under-voltage release) can be snapped on the right side.","metaTitle":"Siemens 5SL6163-6 SENTRON MCB, 1P B 63 A, 6 kA","metaDescription":"Siemens 5SL6163-6 SENTRON miniature circuit breaker, 1-pole, B-curve, 63 A, 6 kA per EN 60898.

The difference is the tripping curve: 5SL6163-6 is B-curve (3–5× In), while 5SL4363-7 is a different characteristic — verify the required curve for the circuit before swapping."},{"question":"What compliance documentation does this brand provide for 5SL6163-6?","answer":"The part carries ratings per EN 60898 and IEC 60947-2 (6 kA breaking capacity).
