At 45 mm wide and 97 mm deep, it fits standard panel cutouts for this frame size.
That's a practical range for motor circuits up to the S0 frame rating — you won't need adapters for typical 2.5 or 4 mm² power feeds. The coil draws 0.25 A at 50 Hz and 0.28 A at 60 Hz; factor that into your control transformer sizing. That covers most indoor panel environments without derating, though you'll want to check the thermal curve if the enclosure runs hot.
The depth is 97 mm, which is standard for the S0 frame size.
It accepts solid or stranded wire from 1 to 10 mm² on the main terminals.
