The 380 V AC coil matches common European line voltages. It is listed as obsolete, so any sourcing runs through the surplus or broker channel — same genuine part, different passport.
The AC-15 and AC-14 utilisation categories tell you this relay is built for switching electromagnetic loads — contactors, solenoid valves, and similar inductive control circuits — not resistive heaters. AC-15 covers solenoid loads above 72 VA; AC-14 covers smaller solenoids below 72 VA. The 4 NO configuration gives you four independent make contacts, each rated for the same duty. The 380 V AC coil is a specific voltage.
