The 220 V AC coil operates at 50/60 Hz, and the built-in 1NC auxiliary contact gives you a feedback or interlock signal without adding a side-mount block.
The AC-3e rating extends that for energy-efficient motors with higher inrush. AC-1 (resistive) is higher but less critical for motor duty.
Dimensions are 86 mm deep, 56 mm wide, 84 mm high, so it fits a typical 45 mm DIN-rail footprint with room for wiring. The IP2X finger protection means it's safe for open-panel use, but not washdown.
