The 230-240 VAC coil is standard for European control voltages. IP20 means finger-safe terminals but no washdown tolerance; it lives inside a panel.
AC-4 rating (inching/plugging) is also listed, so it handles the higher stress of reversing duty where the motor is switched while still spinning. The 1 NC auxiliary contact is built in, giving you a feedback signal for the PLC or a mechanical interlock confirmation. Operating altitude of 2000 m without derating covers most installations; above that, air density drops and the contactor's thermal dissipation and dielectric strength need a reduction factor.
The contactor is rated for 10 Gn shock on the Y and Z axes when closed, and 4 Gn vibration at 5-300 Hz, so it survives moderate machine vibration without dropping out. Flame retardance meets UL 94 V1 and NF F 16-101, so it passes rail and building-material fire tests.
