Rated breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC, which covers most industrial distribution boards fed from a 400 V transformer up to that fault level. The DC rating is 60 V, suited for control-circuit protection on 24 V or 48 V DC rails.
Degree of pollution 3 and overvoltage category III — the MCB is rated for the conductive environment inside an industrial enclosure where condensation or light contamination may occur. IP20 with connected conductors, IP40 in the handle range; the handle area is protected against tools, but the terminals need to be inside a closed panel.
Vibration resistance is 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz, which passes the typical industrial machinery vibration profile.
