Its 8 A rated current and C tripping characteristic mean it handles moderate inrush loads — think lighting banks, small motor starters, or general-purpose socket circuits — without nuisance tripping on start-up, while still clearing a sustained overload within the standard curve. The 6 kA breaking capacity at 230/400 V AC per EN 60898 is the spec that governs fault clearance: it safely interrupts a short-circuit current up to 6 kA without welding the contacts or cascading failure upstream. For a residential or light-commercial panel with a typical prospective fault current under 6 kA, this is the correct coordination point. Overvoltage category 3 and pollution degree 2 confirm it is rated for fixed-installation use inside a distribution board.
At 18 mm width (1 width unit) and 76 mm depth (70 mm installation depth), this breaker occupies a single DIN-rail module. The 90 mm height is standard for the 5SL family, so it aligns with adjacent breakers and busbar systems.
