What this MCB carries
Rated insulation voltage is 440 V, so it's suited for single-phase or two-phase branch circuits up to that line-to-line voltage.
Width is 69 mm (roughly 4 module spaces on a typical rail), height 89 mm, depth 94.5 mm — check your enclosure depth before committing, especially in shallow gland-plate layouts. Screw terminals, IP20 finger-safe front.
