The C-curve (5–10× In) suits it for moderate inrush loads common on motor-starter and contactor circuits in a distribution board. Snap-on DIN-rail mount for standard 35 mm rail. The 4-pole body occupies four module widths (approx. 72 mm) in the enclosure. Terminal capacity accepts up to 25 mm² conductor — verify lug fill factor against your panel layout before committing the BOM.","metaTitle":"Siemens 5SL6408-7BB Miniature Circuit Breaker 400V 6kA 4-pol","metaDescription":"Siemens 5SL6408-7BB miniature circuit breaker, 400 V, 6 kA breaking capacity, 4-pole C-curve, 8 A.
