Rated for panel-board protection at 8 A C-curve
The Siemens 5SL6408-7BB is a 4-pole miniature circuit breaker rated 400 V with a 6 kA breaking capacity and a C-curve trip characteristic at 8 A. 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.
