The IP20 finger-safe enclosure (per VDE 0106) suits it for enclosed panel mounting where personnel contact is possible.
The AC-3 rating of 12 A at ≤440 V governs motor switching. The 220 V DC coil is a specific control voltage; verify your control transformer or DC supply matches this. The 1 NC auxiliary contact provides a feedback or interlock signal. Mechanical robustness is certified to 15 Gn shock (closed) and 4 Gn vibration (closed) per IEC 60068-2-27 and -6, so it holds in on high-vibration machinery like conveyors or compressors.
