The 60 kA Icu at 240 V AC is the interrupting capacity that governs fault clearance on a 240 V distribution board — at 400 V AC that figure drops to 30 kA, so the same breaker covers a 400 V panel only if the prospective fault current stays under 30 kA. The IP40 enclosure and IK07 impact rating suit it for dry indoor panel mounting where accidental tool contact is the main risk, not washdown.
Integration notes
Fixed backplate mounting with a 25 mm connection pitch. The 75 mm width fits standard 3-pole MCCB cutouts; the 130 mm height and 60 mm depth leave clearance for adjacent breakers and wiring ducts.
